He gave the laws of inheritence.
Expiriment: He demonstrated that the inheritence traits in pea plants follow particular patterns.
Genes are located on chromosomes.
Expiriment: Observed chromosomes during sperm formation in grasshoppers.
Discovered that DNA was the molecule of inheritence.
Expiriment: He injected pneumonia into mice to prove that DNA was the molecule of inheritence.
Discovered that DNA serves as genetic material and transmits heredity.
Experimint: Destroyed Lipids, RNA, Carbohydrates and Protiens of Pneumonia, Transformation still occured. Then, DNA was destroyed, and transformation did not occur, proving that DNA is genetic material.
These scientists confirmed that DNA was genetic material.
Expiriment: They infected bacteria with bacteriophages, Their DNA enters the host cell but most of the protien doesn't, showing that DNA is the genetic material, not protein.
Expiriment: Crystallized DNA to make an x-ray pattern. Showed that DNA had a double helix shape.
Discovered the structure of DNA
Expiriment: Used x-ray diffraction data to propose the double helix structure.
