Oswald Avery, Mclyn McCarty, MacLeod
Oswald Theodore Avery (October 21, 1877) was a Canadian-born American physician and medical researcher. Avery was one of the first molecular biologists and a pioneer in immunochemistry, but he is best known for his discovery in 1944, with his co-workers Colin MacLeod and Maclyn McCarty, that DNA is the material of which genes and chromosomes are made. -
Fred Griffith
Frederick Griffith (Born in 1879) was a British bacteriologist whose focus was the epidemiology and pathology of bacterial pneumonia. In January 1928 he reported what is now known as Griffith's Experiment, the first widely accepted demonstrations of bacterial transformation. -
Alfred Hershey, Martha Chase
Alfred Hershey was born in December 4, 1908. Martha Chase was born in November 30, 1927. The Hershey–Chase experiments were a series of experiments conducted in 1952 by Alfred Hershey and Martha Chase that helped to confirm that DNA is the genetic material. -
Erwin Chargoff
Erwin Chargaff (11 August 1905) was an Austrian biochemist.Erwin Chargaff proposed two main rules in his lifetime which were appropriately named Chargaff's rules. The first and best known achievement was to show that in natural DNA the number of guanine units equals the number of cytosine units and the number of adenine units equals the number of thymine units. -
Francis Crick, James Watson
They received the Nobel Prize in physiology or medicine for their 1953 determination of the structure of deoxyribonucleic acid (DNA). Because the Nobel Prize can be awarded only to the living, Wilkins’s colleague Rosalind Franklin, who died of cancer at the age of 37, could not be honored. -
Roslind Franklin
Rosalind Elsie Franklin (25 July 1920) was a British biophysicist and X-ray crystallographer who made critical contributions to the understanding of the fine molecular structures of DNA. -
Meselson and Stahl
The Meselson–Stahl experiment was an experiment by Matthew Meselson and Franklin Stahl in 1958 which supported the hypothesis that DNA replication was semiconservative. In semiconservative replication, when the double stranded DNA helix is replicated each of the two new double-stranded DNA helices consisted of one strand from the original helix and one newly synthesized.
