-
Cross fertilized and self fertilized pea plants and discovered the principles of genetics and how offspring recieve genes from their parents.
-
Crossed double heterozygous plants and proved that genes on the same chromosome are inherited together.
-
Mated fruit flies and discovered crossing over and recombinants.
-
Hypothesized that disease that is inherited affects enzymes. Proposed that there is a relationship between genes and proteins.
-
Performed an experiment on bacterium that causes pneumonia and discovered a "transforming factor" which was DNA.
-
Experimented with orange bread mold and discovered genes and proteins are related. One gene, one polypeptide.
-
Experimented with pairs of DNA's polynucleotide chains. The amount of adenine in the DNA of any one species was equal to the amount of thymine, and that the amount of guanine was equal to that of cytosine.
-
Experimented with E Colt, radioactive isotopes, blenders, and centrifuge. THey discovered that DNA is the heredity material.
-
Experimented with the 3-D structures of proteins and discovered structure of SNA was a helix, x-ray photo.
-
Saw an X-ray crystallographic photograph of DNA and discovered specifically how DNA was structured. They figured out that it was from Watson's thought of how the bases paired.
-
Linked RNA with identical RNA nucleotides with uracil as their base. Deciphered first codon.
