DNA (Deoxyribonucleic Acid) is a genetic material that is present in each and every human being. Every nucleated cell in human body consists of 46 chromosomes, while the sperms of men and the eggs of women contain 23 chromosomes each, which makes a total of 46 chromosomes. Therefore, at the time of conception, every human being born receives half chromosomes from his or her biological mother while the remaining half (23 chromosomes) from his/ her biological father. That is the reason why most of the times a DNA testing is conducted on a person to check the paternity of a person.
The best part of conducting a DNA test is that unlike other bodily tests that are conducted where most of the times we have to provide our blood and undergo painful injection process, in case of a DNA test, one does not necessarily rely on providing their blood. Apart from blood, a DNA test can also be conducted through a strand of hair from a human head, from saliva or even from the nail of a person.
The DNA samples that are provided undergo a thorough procedure that also includes extraction of the cells from the given samples such as blood, saliva, strand of hair etc. The DNA cells are then purified and harvested. The targeted areas of the DNA samples are then copied and when they find a different target area, it is separated from the main one. Once this is done, the results are analyzed. Usually, the entire process is again repeated to double check its authenticity after which the results are obtained and delivered to the person requesting for these tests to be conducted.
The entire process including the report can be available within one week period. DNA tests usually help divorced couples who are willing take their children along with them instead of giving their children to their partner.
