Gregor Mendel
Gregor Mendel's experiment was he breeded pea plants to see how to get one gene or another. His contributions were the law of segragation and dominant and recessive genes. -
William Bateson and Reginald Punnett
Their experiment was they crossed dihybrid heterozygous plants. Their contributions were punnett squares and linked genes. -
Thomas Hunt Morgan
His experiment was bedding fruit flies for eye color. He discovered that white eyes had something to do with males. His contributions were crossing over and genetic recombination. Also gene mapping. -
Archibald Garrod
His experiment was to work with red urine, and discovered that the urine was red because the enzymes didn't break down right. His contribution was the relationship between genes and proteins. -
Frederick Griffith
His experiment was he took mice and put different forms of bacteria in them. Some bacteria was deadly, others were harmless. His contribution was he discovered transformation. -
George Beadle and Edward Tatum
Their experiment was they studied strands of the orange bread mold that couldn't grow on the usual simple growth medium. His contribution was the function of an individed genes is to dictate the production of a specific enzyme. -
Erwin Chargaff
His experiment was he paired different genes with other genes to discover base-pairing. His contribution was he discovered the amount of Adenine in DNA. Also that any species had equal amount of thymine. -
Alfred Hershey and Martha Chase
Their experiment was the radio active DNA and radio active proteins. Their contribution was that they determinded that DNA was genetic material. -
Maurice Wilkins and Rosalind Fraklin
Their experiment was they took an x-ray crystallographic photograph of DNA. Their contribution was they determinded DNA was a helix. -
James Watson and Francis Crick
Their experiment was they made up two polynucleotide strands and used pictures and models to figure out shapes. Their contributions were the double helix and specific gene pairing. -
Marshall Nirenberg
His experiment was he synthesised an artificial RNA molecule by linking together identical RNA nucleotides having uracil as the base. His contribution was genetic codes.
