Barbara McClintock Character Analysis

McClintock was a scientist who discovered “jumping genes” by studying corn genetics. McClintock found that when the corn was stressed, sequences of DNA moved from one place to another and triggered changes in the genome. Though she met much skepticism throughout her career, she was awarded the Nobel Prize in 1983, at age 81, for her work.

Chapter 6 Quotes

McClintock believed that the jumps are a genomic response to internal or environmental stress that cells can't handle under their existing setup. Essentially, a challenge to survival triggers the organism to throw the mutation dice, hoping it will land on a change that will help. That’s what she thought was going on with the corn plants she was studying—too much heat or too little water triggered the corn to gamble its survival on finding a mutation that could help it survive.
