Explanation:

Deoxyribonucleic (DNA) is the basic unit of living organisms which contains genetic information about living organisms. It also contains information about different proteins that make our body. DNA is also responsible for the production of antibodies which helps in the fighting against pathogens such as bacteria and viruses etc. In short, DNA is responsible for every thing that is present in the body of organisms.
