Gregor Mendal
Through experiments with pea plants, he discovered the fundamental laws of inheritance. -
Fredrick Griffith
He performed the first major experiment that led to the discovery of DNA as the genetic material. He figured out that one strand could be transformed, or changed, into the other form. -
Oswald Avery
He identified molecules that transformed the R strain of bacteria into the S strain. -
Erwin Chargaff
Analyzed the amount of adenine, guanine, thymine, and cytosine in the DNA of various species. -
Rosalind Franklin
She produced X-ray crystallography pictures of BDNA. These pictures were later used to let Crick and Watson in their discoveries. -
Hershey-Chase
They published results from experiments that provided definitive evidence that DNA is a transforming factor. -
Linus Pauling
He was the scientist who created the triple-stranded helix. -
Francis Crick
Watson and Crick created the double helix structure for DNA. He also proposed the idea of Central Dogma and Adaptor Hypothesis. -
James Watson
He was in collaboration with Francis Crick with the double helix structure. But he also played a very important role in the development of science policy. -
Roger Kornberg
He figured out the importance of histones to chromatin structure.
