-
Fredrich Miescher
The first to identify the DNA as a distinct molecule. -
Frederick Griffith
Griffiths Experiment was one of the first to say that bacteria are capable are transferring genetic information while in the process of transformation. -
Beadle and Tatum
George Beadle and Edward Tatum came up with the One gene-one enzyme concept which is were genes act through the production of enzymes, with each gene responsible for the creation of each enzyme that in turn affects a single step in the metabolic pathway. -
Max Delbruck
The Fluctuation Test explains that in bacteria, genetic mautaions happen in the absence of selection not in the presence of selection. -
Avery, McCarty and Macleod
This experimantal demonstration explanied that DNA is the substance that causes bacterial transformation. -
Edwin Chargaff
Chargaff created "Chargaffs Rules" which explains that there is always the same amount of Thymine in Adenine and Cytocine in Guanine. -
Alfred Hershey and Martha Chase
Hershey and Chase confirmed that DNA was the genetic material first showed in Avery-Carty-Macleod experiment in 1944 -
Watson and Crick
They discovered the "Double-Helix." -
Rosalind Franklin and Maurice Wilkins
Discovered the structure of DNA and how characteristics are passed down trough generations. -
Arthur Kornberg
He crystallizes DNA polymerase, the enzyme required to synthisize DNA. -
Matthew Meselson and Frank 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. -
Marshall Nirenburg
With Heinrich Matthaei's help; Marshall Nirenburg cracked the genetic code. -
Paul Berg
Berg created recombinant DNA which allows scientist to splice DNA from different organisms and peut them back together. -
Cohen and Boyer
They developed recominant DNA technology showing that genetically enginered DNA molecules can be chaned into foreign cells. -
Kary Mullis
Discovered the Polymerase Chain Reaction or PCR.
