Testing For DNA - Life's Building Blocks

DNA is often called the building blocks of life. It is found in the nucleus of most cells in your body. During reproduction, the baby will inherit half of its DNA from the mother and half of its DNA from its father.

DNA has 4 main parts to it known as a (adenine), c (cytosine), g (guanine), and t (thymine). These parts are arranged in a double helix pattern and the various combinations and areas are what determine everyone's genetic traits and predispositions. Although knowledge of DNA has been around since the early 1950's we didn't have the technology or scientific skill to use it very well until the 1990's. In the 1990's the final secrets of DNA were revealed and we could then confidently use DNA samples from people and match them to offspring, crime scene evidence, and screening procedures. The field of DNA analysis is huge and we are finding out more and more about it every day.

DNA testing is commonly used to determine if a child belongs to a parent, often resulting from the current good IVF Success Rates. This is used for many different applications from paternity tests, custody disputes, child support, or people searching for biological relatives. DNA testing is very reliable and by making sure someone is who they say they are is very easy to do now. The amount of arguing if children belong to a certain person is easily solved and long lost relatives; who show up and ask you for money can easily be denied. Hospital baby mix-ups rarely happen any more but if they do, a simple DNA test is all that is needed to clear it right up.

Forensic scientists rely heavily on DNA evidence right now and you have probably seen a TV drama or two with this being the main focus of the show. Using any bodily fluid or hair, forensic teams can easily pinpoint who the responsible party may be and eliminate 99% of their suspects. This saves an incredible amount of time and money in the legal and law enforcement areas of the world. DNA doesn't lie and is relied on very heavily. There is a minuscule chance that it could be wrong but this is a very small statistic. Many wrongfully accused criminals have been set free and even saved from death row with the implementation of DNA testing.

DNA testing is usually accomplished by non invasive and painless techniques. The most common way for a standard DNA test is to take a swab and rub in on the inside of someone's cheek. This will give a small sample of cheek cells that come off very easily and can be tested. If there is a violent crime involved such as rape, they might need to get a more intrusive sample but it doesn't involve anything painful. Since this is so easy to get, the samples can be analyzed quickly and easily and take less time than your average blood test which many people don't like.

The applications for DNA testing are great and becoming more and more accepted and popular among many nations in the world. As it becomes more popular, the testing materials are widely available and becoming very cheap. It is very easy for anyone who wants a DNA test to go and get one. You can even send away for a test through the internet. Many companies are popping up all over the place that deal only in this type of testing and chances are you have seen a talk show or two about this topic and maybe a commercial for one of these newer companies.
