The working model for DNA was famously proposed by James Watson and Francis Crick in 1953. They described the double helix structure of DNA and suggested how genetic information could be stored and transmitted. Their model built upon the earlier work of scientists such as Rosalind Franklin, whose X-ray diffraction images of DNA were critical in revealing its helical structure, and Erwin Chargaff, who provided insights into the base pairing rules. Watson and Crick's proposal has since been foundational in molecular biology and genetics.
