Genetics in Our Lives: Foundations of Genetics

The video covers key milestones in genetic research, starting with Sutton and Boveri's findings on chromosomes as gene sites. Thomas Morgan's work with fruit flies confirmed these ideas. In 1944, Avery, McClelland, and McCarty proposed DNA as the genetic material, later confirmed by Chase and Hershey. Chargoff identified DNA's chemical proportions, while Franklin and Wilkins photographed DNA. Watson and Crick, inspired by Franklin's images, developed the DNA model, earning a Nobel Prize with Wilkins in 1962.
