DNA stands for Deoxyribonucleic acid, and it is a molecule that contains the genetic code which is used for the growth and development of organisms.
It also controls all the functioning and reproduction of all the organisms that are living. Deoxyribonucleic acid and Ribonucleic acid both are nucleic acids, along with fats, carbohydrates that are complex, and proteins also. There are two stands in DNA that are known as polynucleotides because they are made up of simple monomer units.
