DNA and its role in paternity tests

DNA is the genetic material found in all living beings, is the genetic material that determines its codification by what the individual's physical characteristics, and also determines its biological function.

Due to its function of determining the characteristics of a individup, this genetic material, DNA, has many uses within the field of medicine and health.

For example, you can analyze DNA samples for paternity testing, ie it can perform a DNA test to determine whether a person is a parent of another person.

You can also use DNA analysis to determine the haplogroup, population genetics, and thus a person to know both its history of paternal and maternal lineage ancestry.

Complete copies of this genetic material is found in all cells, tissues and body fluids. That is why analysis is possible with almost any DNA sample of tissue or body fluid.

All the DNA is formed by the combination of 4 base molecule called adenine, thymine, guanine and cytosine. These 4 bases of DNA are represented by their first letter, ie, are represented as A, T, G and C.

These molecules are connected by hydrogen bonds that link pairs of molecules specifically.

These connections of molecules and hydrogen bonds form the famous propeller which represents the DNA, sure you are familiar with this image either science classes at school or by style television series CSI.

The form and sequence in which these molecules are connected encoded instructions that determine our physical characteristics and functions of our body, these instructions are called genes.

It is curious that the markers are analyzed for certain tests such as paternity testing, the study of the lineages, haplogroups and identification of people are in regions of DNA that do not encode genes.

It's amazing to think about how small changes in DNA sequences make one person is so different from another, and can also be used to study such small molecules to determine whether a person is the father of another.
