Watson and Crick's model of DNA, proposed in 1953, revealed the double helix structure of the DNA molecule. This model illustrated that DNA is composed of two intertwined strands, with a sugar-phosphate backbone and nitrogenous bases (adenine, thymine, cytosine, and guanine) paired specifically (A with T and C with G) in the center. Their discovery provided a mechanism for genetic replication and laid the groundwork for understanding how genetic information is stored and transmitted in living organisms.
