Gregor Mendel
Notices traits in pea pants and tests them. Never used to identify DNA -
Friederick Meishcher
Isolated DNA. Never thought it to be genetic material -
Walther Flemming
was the first to detail the chromosomal movements in the process of mitosis. -
William Bateson and Reginald Punnett
They experimented with two characteristics in sweet peas, flower color and pollen shape, and discovered inheritance patterns that were totally inconsistant with Mendelian principles -
Thomas Hunt Morgan
Found out what cross over is -
Frederick Griffith
"Transforming Principal". Knew something was transferred from one cell to another -
George Beadle and Edward Tatum
They experimented by growing orange bread mold and examined strains that wouldn't grow on the usual simple growth medium. -
Oswald Avery
Oswald Avery discovered that DNA is the material of which genes and chromosomes are made. -
Oswald Avery
With Colin Macleod and Maclyn Mcarthy found that DNA was the trasforming principal -
Rosalind Franklin
Hired to improve X-ray crystallography -
Maurice Wilkins
Found the double helix -
Alfred Hershey
With Martha Chase confirmed DNA was the trasforming factor. Radioactive labaling. -
Alfred Hershey and Martha Chase
They infected E-Coli with T2 phage and labeled it with radioactive material so he could tell what was being infected, and proved that genetic material infects and isn't a protein. -
James Watson and Francis Crick
Used Maurice ad Rosalind's ideas and made a model of the double helix. They are credited with the discover. -
Erwin Chargaff
Chargaff's Rule. Determine how the bases are pared. A pairs with T. C pairs with G -
Frederick Sanger
He is known for the sequence of insulin by amino acids -
Frederick Sanger
He is known for the sequence of insulin by amino acids -
Linus Pauling
Pauling developed the theory of the molecular clock, which enables one to judge the separation in time between two species -
Marshall Nirenberg
cracks the genetic code -
ROY BRITTEN
Roy britten and David Kohone found that mouse cells contain multiple copies of very similar dna sequences. -
Gene Theraphy first used
-
Thomas Hunt Morgan
He proved that genes or genetic material is carried on chromosomes by his experiments with fruit flies -
John Sulston
Played a large role in the human genome project
