- Abstract:
Throughout the first half of the 20th century, geneticists assumed that a stable genome was a prerequisite for faithfully transmitting genes from one generation to the next. Working at Cold Spring Harbor Laboratory in the post-WWII era, Barbara McClintock found quite a different story in maize (corn). She observed numerous “dissociations” – broken and ring-shaped chromosomes – and traced the source of these mutations to the short arm of chromosome 9. There she identified two related loci, “dissociator” (Ds) and “activator” (Ac).
