DNA Testing:  A Guide



DNA testing is the process of analyzing the body building blocks which are known as deoxyribonucleic acid. Every living thing contains DNA and genes that are used to govern the way living organism's functions. DNA is different and unique, and that is the reason why it can be used to determine the relationship between two people, the relationship between two plants as well as determining whether a sample is matching with the other.

Paternity testing is the standard use of DNA testing. DNA testing is applied in labs to identify the biological father of a child. It is conducted mostly when a man denies paternity, or they want to know whether they are the biological father of the child. This will help the court to determine the person to cater to the needs of the child as he/she grows.

Forensics labs is another area that mostly depends on the DNA testing. Samples from the crime scenes are collected, and they are run through polymerase chain reaction. This process will amplify them and create larger samples which are made of identical DNA. The DNA of the suspect is then going to be compared with a standard sample dna testing which has been run in the laboratory. If there is any similarity, then the culprit is going to be known. The DNA testing does not necessarily look at the whole strand, but it looks for the matches which are located at specific locations known as loci.

Another function of DNA testing is tracing the maternal history of a person. This is done by use of mitochondrial DNA for it can be passed from mother to her child and there is no change that is going to occur. The first DNA of the two people is going to be examined for similarities, and if the two individuals are related, then the conclusion will be drawn on the family line. Since DNA does not do not change the time it is passed from one parent to the child, the DNA testing can be made available even if the generation has passed. DNA Testing requires being done in a laboratory where sterile conditions. The samples have to be first sterilized to remove any contamination that may affect the results. You can also do the collection of the samples from your home by having dna testing kits uk

This is the most convenient way for you will send the samples to the lab and wait for the results while from your home. For more facts and information about DNA profiling, you can go to http://www.ehow.com/how_5037940_start-blood-testing-clinic.html .
