Full form of DNA is Deoxyribo Nucleic Acid and is pronounced as dee-oxy-rye-bow-nu-clee-ik acid.
Deoxyribonucleic acid (DNA) is a nucleic acid that contains the genetic instructions used in the development and functioning of all known living organisms and some of the viruses as well. DNA stores the instructions which are needed to construct other components of cells, such as proteins and RNA molecules. The DNA segments that carry this genetic information are called as genes.
The DNA code is made up of four chemical bases:
They are joined by hydrogen bonds between the complementary bases. Adenine pairs with Thymine or Cytosine pairs with Guanine
Does it sound tough? Here is simple explanation:
How a child does inherits the same physical characteristics from parents? It is through DNA. Since DNA contains genetic instructions required for development of living organisms, these are how they get similar physical characteristics as that of their parents.
Enough of insides of DNA? Let us now understand what DNA test is and how it is used in forensic investigations.
DNA testing is a powerful way for knowing who the biological parent of a child is. It is also used in Forensic testing to identify suspects or victims in a criminal investigation. DNA test is so precise and accurate that it can ensure accuracy to one in a billion. Unlike fingerprints, which can only be found if a criminal touches something, DNA exists in every cell of the human body. It exists in hair, blood, skin, tears or any part of the body and it can be shed or deposited while committing a crime. With the help of shed DNA it is easy to find the person who committed the crime and as said above, the accuracy is to the level of one in a billion. But here is a catch. Though every person has a unique DNA but twins may have same DNA. We inherit half of our DNA from our biological father and half from our biological mother. So, paternity test can find out easily who the father is and who the mother of a child is. In fact, paternity test can be done even before the child is born. So, before child’s birth itself it can be identified who is the father of the child who is going to be born.
