James Watson

Definition

James Watson is an American molecular biologist, geneticist, and zoologist best known for co-discovering the double helix structure of DNA along with Francis Crick. This groundbreaking work laid the foundation for understanding the central dogma of molecular biology, which explains how genetic information is transferred from DNA to RNA and ultimately to proteins, essential for life.
