-
Gregor Mendel
Published the results of his study on pea plants and the fundamental laws of inheritance. -
Friedrich Miescher
The first to discover that DNA is a molecule. -
Frederick Griffith
The first to experiment that bacteria is able to transfer genetic information through transformation. -
George Beadle
Discovered the role of genes that take place during biochemical events in a cell. -
Oswald Avery Jr.
Indicated that DNA was the carrier of genes in cells, his experiments made way for Watson and Crick's discovery. -
Edwin Chargaff
Found that the amounts of adenine and thymine as cytosine and guanine in DNA. -
Martha Chase
Performed an experiment that proved that DNA was not a protein and that it in fact was genetic material in which traits were inherited. -
Alfred Hershey
Performed an experiment that proved that DNA was not a protein and that it was genetic material in which traits were inherited. -
Rosalind Franklin
Took images of DNA and essentially because of these images, is the one who discovered the structure of DNA known as the "double helix" but she never got credited. -
Maurice Wilkins
Worked along with Rosalind Franklin who took images of DNA and its structure, but unlike Rosalind Franklin she was credited along with Crick and Watson. -
Francis Crick
Discovered the structure of the DNA is a double helix after taking over the images from Rosalind Franklin and later received the Nobel Prize along with Watson for this discovery. -
James Watson
Discovered the structure of the DNA is a double helix after taking over the images from Rosalind Franklin and later received the Nobel Prize along with Crick for this discovery. -
Sydney Brenner
Proved, by using statistics and amino acid protein sequences, that three nucleotides code for one amino acid. -
Matthew Meselson
Used E. Coli DNA to discover that DNA replication is semi- conservative. -
Franklin Stahl
Used E. Coli DNA to discover that DNA replication is semi- conservative. -
Edward Tatum
Discovered the role of genes during biochemical events in a cell. -
Paul Zamecnik
Alongside with Mahlon Hoagland, Paul Zamecnik discovered tRNA. Then Paul Zamecnik and Mahlon Hoagland discovered that ATP had to be activated to become a peptide chain. -

Marshall Nirenberg
Discovered the first sequence of three bases which is a codon. -
David Baltimore
Discovered reverse transcriptase which is an enzyme used to create DNA from an RNA template. -
Howard Temin
Discovered reverse transcriptase which is an enzyme used to create DNA from an RNA template.
