GENETICS Barbara McClintock (Estados Unidos, 1902-1992)
One of the greatest scientific reseachers of genetic field, she was Nobel Prize of Medicine in 1983, even thought it wasn't easy as a woman reseacher. Her innovating results came from the corn and her searching of the human genome. McClintok watched the "letters" that composed her DNA and saw, for the first time, that exists a serie of genetic sequences which could change its position. So, she produced the first genetic map of the corn, that later it was used to demonstrate the working of the process and the genetic regulation.
