DNA—Watson-Crick Model and Biological Importance (With Diagram)

In this article, we propose to discuss the Watson-Crick Model of DNA and biological importance of DNA. DNA is the largest macromolecule that represents the genetic material of the cell. Chemically, DNA is a double helix of two antiparallel polynucleotide chains. Each polynucleotide chain is a linear mixed polymer of four deoxyribotides i.e. deoxyadenylate, deoxyguanylate, deoxycytidylate and thymidylate. Watson-Crick Model [...]
