-
Friedrich Meischer
He isolated nuclein from the cells nuclei. he was the first to identify DNA as a distinct molecule. -
Frederick Griffith
He made the first experiment suggesting that bacteria transfers genetic material. -
Oswald Avery, Maclyn McCarty, and Colin McCleod
They discovered that genes are made up of DNA. And, they showed that they can transform the properties of cells. -
Barbra McClintock
She discovered the mobile genetic element, or as they call it "Jumping genes". -
Erwin Chargaff
He discovered that DNA is the primary constituent of the gene. -
Rosalind Franklin and Maurice Wilkins
They discovered that DNA was shaped like a twisted ladder. -
Alfred Hershey and Martha Chase
They proved that DNA carries genetic material. -
James Watson and Frances Crick
They used the idea of the shape, double helix, and made it their own. -
Linus Pauling
He discovered the spiral structure of proteins. -
Frederick Sanger
He discovered the structure of an insulin molecule. -
Matthew Meselson and Franklin Stahl
They confirmed that Watson and Crick's hypothesis of DNA replication is semiconservative was true. -
Paul Berg
He, Walter Gilbert, and Frederick Sanger discovered the development of the recombinant DNA techniques. -
Kary Mullis
He discovered the polymerase chain reaction which allows chemists to produce many copies of DNA. -
J. Craig Venter
He is known for being involved with the second draft of the human genome sequence and he assembled the first team to transfect a cell with a synthetic chromosome.
