However, in the 1930s and 40s, McClintock's work showed that some genes did not exist in fixed position on chromosomes, but could actually jump around from one part of the chromosome to another. She attencled every session of From the late 1920s, McClintock studied chromosomes and how they change during reproduction in maize. She was vindicated, however, later in the 1950s, when molecular biologists, using powerful new tools (crystallographic techniques and X-ray diffraction patterns), found the basic double helix structure of DNA, which comprises genes. in 1983.

The association of non-homologous parts of chromosomes in the Inthe 1960s and 70s,independent groups of scientists began to describe genetic regulation and thephenomenon of transposition in bacteria. By meticulously crossbreeding corn, McClintock showed that DNA is far more complicated than scientists originally thought.

During the 1920s, researchers at Cornell's College of Agriculture were investigating plant genetics, using maize (Indian corn), an ideal plant to analyze because kernels come in a variety of colors, blue, brown, and red, indicating to the naked eye that changes occur from generation to generation. Because each style has its own formatting nuances that evolve over time and not all information is available for every reference entry or article, Encyclopedia.com cannot guarantee each citation it generates. In the U.S., women comprised between 30 and 40% of all graduate students during the decade, and accounted for approximately 12% of the science and engineering Ph.D.s awarded, a proportion not seen again until the 1970s.

These elements, which regulate the expression of different genes and traits at different stages of development and allow different cell types with the same genome to have different patterns of gene expression, actually sit next to the genes they control and stay put.

However, there were two genetic elements that McClintock could not locate on the chromosome and concluded that this was because they were not fixed to one particular position they appeared to be jumping around the chromosomes and explained why some corn had a mosaic pigmentation pattern rather than being one solid color.

Only two other women had become members in 81 years. From 1958 to 1960, McClintock trained cytologists from Latin America to collect and identify indigenous maize, because modern maize seeds were crowding out the native strains.

Though she had excellent research privileges, she was not treated well and never felt a part of the faculty, despite the fact that her reputation as a geneticist continued to grow.
