The research and discovery

  • research was conducted from 1941-1950
  • work was conducted at cold springs
  • worked alone, as she wasn't a very social person
  • discovered genetic transposition
  • noticed different colored spots on leaves on a corn plant, she researched it
  • guessed that some kind of a mutation occurred in the early stages of growth
  • when work was published, many of her colleagues disagreed with her
  • eventually in the 1970's, advancements in technology were able to prove what she had discovered
  • in 1983, she won the noble peace prize for physiology or medicine for her work

The importance

Her discovery opened up research in the field of genetic and led to many discoveries. It also served as a possible basis for how cells changed into cancer cells and helped us understand about human diseases. It effects us today because we are still trying to find a cure for cancer, and helped us develop antibiotics.
