DNA is the abbreviated form of deoxyribonucleic acid which is a representation of the hereditary material of human beings as well as other living organisms (Russell, 2001, p.69). All living organisms contain the DNA material in their body make up. It is therefore the unique material that is used to differentiate people from others or even other creatures. For example, human beings will have a different genetic makeup from that of plants and animals.
In addition to this, human beings will have different genetic makeup from other human beings unless they are of the same family chain. The DNA serves as storage of the genetic information in the form of codes. DNA information is thus of great importance in several matters and issues facing all living creatures such as research, breeding, paternity tests among others. This paper is therefore an in-depth analysis of the DNA structure, components, how it works and importance.
