DNA

What is DNA?

DNA stands for Deoxyribonucleic Acid and DNA is the molecule which is located within the nucleus of the cell, and its main job is to preserve and code the genetic information of the body. For most of the life cycle of the cell, the DNA is situated in the cell nucleus like a coiled noodle. But at some stage, while the cell replicates, the DNA is organised in the form of structure, namely chromosomes. The chromosomes help in preserving the stable DNA in the course of the time of the cellular replication. Now, most of you are familiar with the double helix model of the DNA.

The double helix version demonstrates that DNA is a polymer. To understand DNA, you have to review the definition of a polymer. The polymer is a molecule made up of several identical repeating units, and each unit is referred to as monomers.
