-
Notices traits in pea pants and tests them. Never used to identify DNA
-
Isolated DNA. Never thought it to be genetic material
-
was the first to detail the chromosomal movements in the process of mitosis.
-
They experimented with two characteristics in sweet peas, flower color and pollen shape, and discovered inheritance patterns that were totally inconsistant with Mendelian principles
-
Found out what cross over is
-
"Transforming Principal". Knew something was transferred from one cell to another
-
They experimented by growing orange bread mold and examined strains that wouldn't grow on the usual simple growth medium.
-
Oswald Avery discovered that DNA is the material of which genes and chromosomes are made.
-
With Colin Macleod and Maclyn Mcarthy found that DNA was the trasforming principal
-
Hired to improve X-ray crystallography
-
Found the double helix
-
With Martha Chase confirmed DNA was the trasforming factor. Radioactive labaling.
-
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.
-
Used Maurice ad Rosalind's ideas and made a model of the double helix. They are credited with the discover.
-
Chargaff's Rule. Determine how the bases are pared. A pairs with T. C pairs with G
-
He is known for the sequence of insulin by amino acids
-
He is known for the sequence of insulin by amino acids
-
Pauling developed the theory of the molecular clock, which enables one to judge the separation in time between two species
-
cracks the genetic code
-
Roy britten and David Kohone found that mouse cells contain multiple copies of very similar dna sequences.
-
-
He proved that genes or genetic material is carried on chromosomes by his experiments with fruit flies
-
Played a large role in the human genome project
