Biological science developed immensely since Charles Darwin's evolution theory. Although for a period of approximately a decade biological science had remained a mystery. The way we, human beings, survive was by itself a big query. The mystery regarding origin, development and extermination has lingered for an extended duration. Genetic studies resolved the very old biological mysteries. A separate scientific branch termed genetic biology began its effort to solve mysteries of existence. Darwin demonstrated the course of evolution and genetics uncovered our voyage throughout that course. Gregor Mendel with the help of his studies on inheritance showed us the way to genetics. The study of genetics revealed the DNA, the fundamental component for inheritance. There're many studies accomplished on DNA and more on course now.
DNA stands for Deoxyribonucleic acid. They reside in every living being and store information on growth and operation. A few viruses are exception. You may regard DNA to be outline of our life storing information. In fact the elements of DNA called the genes store this information. The additional elements of DNA make it up and control other information. The element that makeup the DNA is known as double helix. You might be wondering the way the DNA forms. The zygote is formed within a mother's womb when a male's sperm fuses with a woman's ovum. There are 36 pairs of chromosomes in a zygote, 23 pairs come from the mother and 23 pairs come from the father. Inheritance of nature and resemblance of look etc. comes from the chromosomes which contain the DNA.
That's why when a question of parenthood of a child arises it can be solved by testing the DNA which is 99.9 percent foolproof. Sometimes if question arises about the legal heir of a deceased person it can be solved by DNA test which is called DNA finger printing. Additional cases have been found in which a person asserted his/her right over an asset with a clause that he/she is the lawful heir of the dead person who was the owner of the property. After the death of a person DNA can be available from his heir or fingernail as DNA does not get decomposed quickly.
DNA paternity test is accepted worldwide. As biological parenthood can be determined by DNA testing so many controversial civil and criminal cases are able to be solved by using it. Also controversy as to whether biological parenthood claim is authentic can be taken care of.
