Friedrich Friz Miercher
He was the first person to have a crude representation of DNA. He called it nuclein. -
Hugo de Vries
He used flowering plants to rediscover Mendle’s law. Having the microscope helped the idea of cells become more widely accepted. -
Herman Muller
He used X-rays to cause mutations in the reproductive DNA of flys. -
Barbara McClintock
She believed that genes could destabilize and “jump” out of place leaving a copy that when passed down to the “daughter” gene would become more distorted the farther along it went. -
Oswald Avery
Found out that pneumonia bacterial strain S could recreate itself with an R strain so long as it still had its DNA left. -
Erwin Chargrff
He found that DNA is made up than more than just simple repetitive tetranucleotide blocks. -
Rosalind Franklin
Used X-ray diffraction patterns to learn more about DNA molecules. This eventually lead to 3D modeling of DNA. -
Hershy-Chase
They experimented with phages and how it reproduces through injecting its DNA into the bacteria. They concluded that DNA is genetic material. -
Linus Pauling
He had the idea of a triple helix. He forgot however that the negative oxygen atoms would repel each other. -
Watson-Crick
They experimented with phages and how it reproduces through injecting its DNA into the bacteria. They concluded that DNA is genetic material.
