-
Gregor Mendel
He discovered the trend between parent and daughter cells. -
Friedrich Miescher
He discovered the nucleic acid. -
Fredrick Griffith
He discovered that DNA is a molecule of inheritance. -
Thomas Morgan
He proved that genes or genetic material is carried on chromosomes by his experiments with fruit flies. -
Erwin Chargaff
Noticed a pattern in the four bases: adenine, guanine, cytosine, and thymine. He invented the "Chargaff Rule." -
Oswald Theodore Avery
discovered that DNA is the material of which genes and chromosomes are made. -
Maurice Hugh Fredrick Wilkins
He discovered the structure of DNA and made the first accurate, detailed model of DNA. -
Hershey & Chase
Discovered that DNA was genetic material, and the DNA of the phage virus contains the phage genes. -
Watson and Crick
They were the two co-discoverers of the structure of DNA. They used x-ray diffraction data that Rosalind Franklin collected. With this information they proposed the double helix structure of the DNA molecule. -
Rosalind Franklin
She determined the B-form of the DNA helix and the location of phosphate groups on the outside of the structure. -
Frederick Sanger
Created the dideoxy method of sequencing DNA. -
John Sulston
He is most famous for finding out how cells in C. elegans divide.
