Famous Biologists

Mendel made several significant contributions to the world of genetics. The first was his discovery of the recessive and dominant traits of "heritable traits" or genes, as we now call them. He found, by breeding pea plants, that certain genes were dominant over others, and that the characteristics of the dominant gene would take effect over the characteristics of the recessive gene. Another one of his discoveries is the Law of Segregation that states that …

…DNA was the genetic material. But he was the first person to transfer a gene from one organism to another. Watson and Crick discovered the structure of DNA by fiddling with cardboard models of DNA developed by studying x-ray crystallography pictures taken by Rosalind Franklin. Crick discovered the natural attraction between a-t and c-g, and Watson theorized that the base pairs of a-t and c-g formed rungs on the twisting double helix ladder of DNA.
