Friedrich Miescher
Frist to describe the apparence of DNA. -
Fedrick Griffith
First to describe DNA -
Linus Pauling
He developed an electron gravity scale, assigning numbers to how powerful the covalent bond is. -
Oswald Avery, Maclyn McCarty and Colin McCleod
Discovered that DNA is the transforming principal / material of heredity -
Barbara McClintock
Proved genetic elements can change position on the chromosome, causing nearby genes to become active or inactive. -
Erwin Chargaff
Found out the amount of thymine and adenine are identical to the amount of cytosine and guanine. -
Alfred Hershey and Martha Chase
Proved DNA, not proteins, satisfies the frist property of a hereditary molecule. -
Rosalind Franklin and Maurice Wilkins
Determined the structure of DNA using X-ray crystallographic technology. -
James Watson and Frances Crick
They determined that the structure of DNA was a double-helix polymer, each containing a long chain of necleotides wound around eachother. -
Matthew Meselson and Franklin Stahl
Verified Watson’s and Crick’s model for the structure of DNA. -
Paul Berg
Discovered genetic splicing which slices DNA and combines the strand with other strands of broken DNA. -
Frederick Sanger
Developed the Sanger Method to figure out the order of bases in a DNA strand. -
Kary Mullis
Invented the polymerase chain reaction, which is the reaction where DNA connect with eachother to form a long chain of DNA. -
J. Craig Venter
Developed the EST method for finding genes using a genome model.
