Watson and Crick model

Watson and Crick's model describes the structure of DNA, the molecule carrying genetic information. They proposed the double helix shape, resembling a twisted ladder. The sides of the ladder are formed by sugar and phosphate molecules, while the rungs consist of paired nitrogenous bases (adenine with thymine, and guanine with cytosine). This model explains how DNA replicates and stores genetic information, contributing to our understanding of heredity and biology. Their discovery in 1953 has been foundational in genetics, impacting fields like medicine, forensics, and evolutionary biology.
