Analysis of DNA in Paternity Testing

The paternity testing (determination of parentage) is to judge existence related to a biological parent and child by a scientific method. The organism is continuing the life activity by telling the gene from parents to the child. It is the one that is called the main body of the inheritance material that puts the genetic code DNA (deoxyribonucleic acid), and it is sure to exist in almost all cells. The genetic code of DNA encrypts the array of the molecule of four kinds of bases of A (adenine), T (thymine), C (cytosine), and G (guanine), is told, and there is an individual variation in this array. Our having a different respectively feature has come from the difference of the genetic code of this DNA. A locus has two allelic genes in the human chromosome, and is a gene of the father origin and each mother origin. As for the DNA test, it divided into the paternity testing by a past blood type by the one to analyze the feature of the base sequence with this individual variation and the judgment with high accuracy that was able to be trusted was possible by an ultimate high technology
