DNA sequencing is the process in which scientists find the sequence of the building blocks of a strand of DNA. Those building blocks in each strand are called nucleotides, each of which is assigned a letter; A (Adenine), C (Cytosine), G (Guanine), and T (Thymidine). Each strand of DNA is a double strand and are contained within cells. Each time a cell splits, so does a strand of DNA. Each single side of the strand will then replicate itself. During this replication, another completed double strand of DNA is formed, which is an exact replica of the first.
The DNA sequencing is what pre-determines the genetics of every living thing. Each gene has its own unique strand of DNA sequencing. Scientist are able to determine the exact DNA sequencing of certain genes by taking a tiny strand and putting the sequence into a computer, which can produce a 3D model of the gene. You cannot go out and purchase a DNA sequencing kit like you can buy a bottle of cologne, but through government grants and funding, the scientists who study DNA sequencing are able to use this technology to determine what goes wrong with a gene that causes diseases and deformities.
Almost everything that is alike has the same DNA sequencing except for a few small genes that determines their minor differences. Humans, for example, will have the same genetic makeup as their ancestors, apart from the small genes that give them a different hair color or shape of their ears. This is why we tend to look like our parents and grandparents, because we have mostly the same DNA sequencing as they do. This is also how DNA sequencing is used to determine paternity.
DNA sequencing is done by scientists in a very precise manner. First the DNA must be extracted from the chromosome that houses it, and then broken up into smaller strands. Each small strand is used to make a set of fragments, each one base (two opposing nucleotides in a strand) shorter than the one before it. The fragments are separated by a gel and then a fluorescent dye is used to identify each individual type of nucleotide. A computer program then generates the sequences of the nucleotides into units of about 500 bases that exactly replicate the strand that the DNA was taken from. These units are then replicated to make a very long strand of DNA sequencing. The resulting DNA sequencing is then shared with other scientists in computer databases.

* How To Choose Where You Buy A HDTV Set From
When considering where to buy an HDTV set, we can easily think, online is the best option. However, this is not always the best option. It comes down to your needs. And they are important to look at.
There are some things to consider before deciding to buy from a particular store:
- Do they offer the best prices?
- Do you get a warranty?
- How will you get the TV to your home?
For online:
- Do you need help with terminology, technology, etc?
- Is there an easy way to get help?
- Do they reply to your queries quickly?
- Is there a phone number and address - just in case if things go wrong?
- Do they ship to your location, and at what cost?
Research is always the key to getting a great deal. It may seem like a lot of work, however, it can benefit you in big ways. Imagine buying a HDTV set that retails for $1,500. You may be able to save approximately $100 to $300 by doing research that may take an hour or two. Unless you earn hundreds of dollars an hour, the investment in research can go a long way.

The Is No Shortage Of Wireless Ringtones
In today's fast paced world, people rely on their cell phones to keep in touch and just about everywhere you look it is easy to spot people who have their cellular phones nearby and at the ready. With such an abundance of mobile phones out there and being carried by everyone from grade schoolers to grandmothers, wireless ringtones are something we have all become accustomed to hearing.
But, because of the popularity of cell phones and the fact that they are ever-present and even ubiquitous in modern life, there is also a great need for people to make their phones somewhat personalized and make a statement about who they are. Unique ringtones are one of the ways that people make their phone, and themselves, stand out from the cellular crowd.
In addition to helping to customize a phone to an individual's tastes, there is an even more practical reason why people seek out new downloadable ringtones. In a crowded room, personalized wireless ringtones simply help people to quickly figure out if it is their phone that is ringing or another.
Who hasn't either seen or been part of a scene when a cell phone suddenly starts ringing and the whole conversation comes to a grinding halt while people reach for their phones to see if they are getting the call. With the vast array of free mobile ringtones that are available these days, this type of scene is not happening as often because people are using more unique ringtones.
Ringtones are available in a number of ways these days. First, your wireless phone usually comes with a number of ringtones already installed. But in many cases, people are dissatisfied with the choice of caller ringtones because they tend to be very generic and there is not much of a choice. After activating the cell phone there are usually some additional cellular ringtones that you will be able to download, either from the cell phone service provider's website, or directly on your phone, depending on the type of cell phone service you have.
However, in most cases the cellular phone ringtone selection offered by the providers is often still very limited and the users quickly discover that they just don't have much in the way of choices to really reflect their personality. Sometimes, the cellular customer discovers that they have to pay for the best downloadable ringtones, such as popular real music ringtones that are becoming more and more in vogue.
The good news is that there is no shortage of available wireless ringtones that you can download and add to your phone. Some of the websites that enjoy the most internet traffic everyday are the ones that let people access free downloadable ringtones. Regardless of what you are looking for in a cellular phone ringtone, with a little searching on the net you will most likely be able to find something that you love.

Find Out What Notebook Is Right For You
The Netbook has sprung onto the market with force thanks to the new Intel Atom processor that allows you to stay connected for longer. So which of the 10-inch models is the best for you? We take a look at three of the contenders in the field.
MSI Wind notebook
Following hot on the heels of the Eee PC the MSI Wind, yet another white plastic netbook. Pull open the lid and you will be presented a 10-inch Super-TFT panel and an almost full size keyboard. Operating systems are either Windows XP or Linux.
As for that chip, the Intel Atom N270 runs at 1.6GHz but as the core of the chip is based on older technology, so you won't see much of a performance boost over the Celeron chips found in the Asus. However, as it runs at a lower voltage, it impacts less on battery life. The new chip improves usability but not performance making the MSI Wind a winner in our book. It's taken everything Asus learnt from its first generation Eee PC and improved on it.
Advent 4211 notebook
It is impossible to review the Advent 4211 without referring to the MSI Wind, but perhaps there is no need because the Advent 4211 is identical. The difference lies in the price, the colour schemes and bundled software. The Advent comes in a black outer shell, with silver interior.
The Advent 4211 is home to the same Intel Atom N270 chip as used in the Wind and this gives you 1.6GHz processing power. The display is a crisp 10in LCD (1024 x 600) LCD, which stands up fairly well in a range of light conditions, both indoors and out.
The keyboard is obviously small, but fills the width of the frame so maximal space is given over to the keys. As there is no optical drive, you'll either have to download the software you want, or install from a USB stick or SD card. The Advent 4211 is a great little computer and runs very well.
Asus Eee PC 1000 notebook
It is seems that every time a company announces a rival to Asuss Eee PC crown, the Taiwanese company sees this as a direct challenge and announces another model in the Eee PC range.
So, hot on the heels of the 901 comes the 1000. It takes the same styling as the 8.9-inch model, but features a 10-inch screen. This larger screen does mean the overall design is bigger and heavier. Sure, 1.5kg is still ultraportable but when you think back to the 701 and its sub-1kg size it is easy to see that the idea of true portability is slipping away.
The only problem with have with the Eee PC 1000 is the size of it. The largest Eee PC to-date, the 1000 may be suffering from size creep but it is still a fantastic machine to use. The battery life is impressive and the build quality is still as high as ever.
The only problem is, you need ask yourself, at this price, would you be better off opting for a standard notebook? Looking at the evidence the answer is no.

Home Cinema: A Nail In The Coffin Of The Talkies?
Since the Lumiere brothers screened their first cinematograph images in 1895 the world has been involved in a steamy love affair with moving images. It has survived world wars and oppressive regimes, and it has been used for educating and indoctrinating alike. Coinciding with the development of the railways the moving image was always representative of modernity and it is one of the only industries to keep developing its technology constantly through a process of creative problem solving.
It is a unique blend of art and commercialism, with the global industry worth tens of billions worldwide however certain industry professionals still manage to maintain their creative stamp on the films they create within this stringent commercial framework. As the film industry has developed so has many associated industries. As the capture of film became better quality so did the screening processes and it was not long before this was made accessible to the average household.
Starting with 8mm cameras and projection systems home cinema was born in the 1950s and 1960s. This was followed by super 8mm film in the 1970s and then the infamous Laserdiscs and Betamax in the 1980s. These domestic appliances brought the moving images of the cinema into the home and many industry commentators predicted the demise of the cinema or the talkies as they were dubbed post-sound.
Luckily for all home cinema enthusiasts the home cinema industry has developed significantly throughout the last two decades, moving from VHS, super VHS to DVD and pay per view delivering pre-DVD released movies directly into the home at the click of a remote. So how has this affected the film industrys box office takings? The answer is not a great deal.
When scrutinising the British Film Institute figures for cinematic admissions over the last 70 years you can see that in 1946 the attendance peaked with 1,635 million people going to the cinema, however ten years later they had dropped to 1,100.80 million. Then over the next three years the attendances plummeted 581 million, a total decrease of over 1000 million from its peak. When weighing this up against the development of home cinema technology it does not match up.
What it does fit with nicely is the rise of television. BBC 1 first broadcast in 1936 when domestic televisions were not commonplace however by the launch of ITV in 1955 the British economy was recovering and more people had TV sets. Partner this with fact that the majority of the attendances during UK wartime were there to watch news reels which were now being made available through TV then you have a plausible explanation for the drop in cinema attendances.
When examining the more recent cinematic attendances we can see a trough in 1984 at a measly 54 million during the VHS generation of home cinema which was first introduced in 1976. From then on the number of cinema attendances has been on the rise despite massive technological advances in home cinema. Now with DVD, HD, plasma screen and surround sound surely people would have everything they need at home?
The answer is again no. As we see from the Cinema Exhibitors Association, attendances between 2000-2007 have maintained a constant figure of around the 160 million region, a massive increase from the economically turbulent late 80s and early 90s. The fact is that the cinema is so embedded in UK culture and around the globe that it can never be replaced by any affordable home cinema. The psychology of the collective spectator, the confectionary and pure sensory magnitude of the experience will see cinema attendances stretching into the next millennium and beyond.

Radar Detector Protection For Those Speed Traps
Oh, no. Too fast. You're motioned to pull over. You pull over and watch as people slow down to watch, probably thinking they're glad it wasn't them. After receiving your ticket, you swear you're going to buy one of those gadgets that sound an alarm that there is one in use up ahead.
This is where it gets tricky. You're going to need a real modern one if you want to avoid this happening again and one you can afford. Times have changed since the old ones used radio waves as a means of detection. Today's laser guns are much more efficient and harder to detect. Today there seems to be a vast selection of popular detectors to buy. Listen, you can always send this baby back for a new updates, but the even buying a brand new one, it's probably the same components as the first one which is still just as effective.
Now most people are usually upstanding citizens and follow the letter of the law, but I don't know too many people who haven't been stopped for speeding, including me, so the easiest thing to do is pay attention to how you're driving. It's easier said than done, so the best thing to do if you're not as attentive, is to purchase a radar detector just to be on the safe side. Then you don't risk being pulled over and get that ticket.
Safety on the road should be the prime concern of every driver and the laws of driving and speed limits are in place for good reasons, so always be prepared for speed changes and don't be heavy with your foot, but keep in mind that we all have been guilty of not concentrating and a radar detector can come in handy, especially when traveling on an unfamiliar road.
Even though many of the speed cams are popping up on the freeways in the city there are still many speed traps which we find ourselves going a little to fast.
If you want to avoid that citation and avoid paying the fine that this entails, plus save yourself some embarrassment, safeguard yourself in all areas, so this would include utilizing a radar detector and some of the best are can be tracked down online, and for heaven's sake, don't wait until after you receive a speeding ticket. It just might be one of your better investments for your car. Just friendly words of advice.

How Telecommunication Have Advanced Over The Years
When someone mentions the word telecommunications equipment, the first image that springs into the mind of a layperson is a telephone. While this is somewhat accurate in most parts, it is the process of transmitting data over a distance using signals for the purpose of communication or exchanging data information. A telephone is one method of transmitting this information, though this is the most common way of communicating with someone else by vocally exchanging information.
Telecommunications equipment comes in various different forms and not just as a telephone handset. The following are a form of telecommunications equipment, radio, television, internet, computer networks and mobile telephones. These provide data and information in very different ways from each other. Some are designed for visual information, such as the television or computer devices. Televisions are common in practically every home, making it the main form of quick entertainment and fast communicator for vital pieces of information.
Everyone are familiar with a computer and are aware of how this is a more accurate way of receiving messages, obtaining important information and communicating with people over longer distances. Often this can be a more reliable source for trying to reach people, whereby a telephone may not receive and transfer signals well. In the past, making long distance phone calls required much more time to connect, as well as more concentration on trying to listen to each other speak.
The internet is a great source for providing effective communication using voice over internet protocols, such as Skype, MSN Messenger, Vonage, BT and PlusTalk. These are just some of the biggest internet telephony providers, which allow users to connect to and contact other internet telephony users provided they have an account set up and have exchanged profile information with the other party. The difference is there is not always a telephone provided for most of the software (Skype had introduced Skype Phones for users wanting to call landlines) and the connection is via a broadband internet connection.
Telecommunications equipment have taken a step further into allowing people who are deaf or hard of hearing to contact other people using video telephoning, which most telephone company providers offer with their prices. This is ideal especially for people looking to make social calls and can use their sign language skill for effective communication. These come at no further charge and calls are at the same price as normal landline calls.
Some telephones have a specific operating system, which allows you to text, or communicate with an operator through typing. These are ideal for those who cannot afford video telephoning. Text messages on mobile phones and using the internet is another useful tool for people with hearing disabilities to communicate with other people. Instead of perceiving them as expensive objects, they are now an important of our daily living, which means they need to be quicker at transmitting information and accessible to everyone.
These kinds of telecommunication equipment have seen changes from improved audio quality to clear picture quality that allows people to see each other in real time. This is a far cry from the days of sending smoke signals and sending hand-written letters.
