Gregor Mendel
Through his work on pea plants, discovered the fundamental laws of inheritance. He deduced that genes come in pairs and are inherited as distinct units, one from each parent. -
THOMAS HUNT MORGAN
He was able to established the chromosomal theory of inheritance -
HERMANN MULLER
Showed that X-rays could induce mutations in living organisms if the had enough radiation -
oswald avery
He had isolated DNA as the material of which genes and chromosomes are made. -
Erwin Chargaff
he had isolated DNA from different organisms and measured each of these levels of each of the 4 nitrogenous bases -
Rosalind Franklin
Produced the X-ray crystallography pictures of BDNA which Watson and Crick used to determine the structure of double-stranded DNA. -
Hershey-Chase
Blender experiment that proved phage DNA, and not protein, was the genetic material -
James Watson, Francis Crick.
James Watson and Francis Crick came up with the structure for DNA -
Frederick Sanger
He was the first person to obtain a protein sequence. By doing so, Sanger proved that proteins were ordered molecules and by analogy, the genes and DNA that make these proteins should have an order or sequence as well. -
MARSHALL WARREN NIRENBERG
He was able to discover what to do for cracking the genetic code
