- 
  
  He discovered the trend between parent and daughter cells.
- 
  
  He discovered the nucleic acid.
- 
  
  He discovered that DNA is a molecule of inheritance.
- 
  
  He proved that genes or genetic material is carried on chromosomes by his experiments with fruit flies.
- 
  
  Noticed a pattern in the four bases: adenine, guanine, cytosine, and thymine. He invented the "Chargaff Rule."
- 
  
  discovered that DNA is the material of which genes and chromosomes are made.
- 
  
  He discovered the structure of DNA and made the first accurate, detailed model of DNA.
- 
  
  Discovered that DNA was genetic material, and the DNA of the phage virus contains the phage genes.
- 
  
  They were the two co-discoverers of the structure of DNA. They used x-ray diffraction data that Rosalind Franklin collected. With this information they proposed the double helix structure of the DNA molecule.
- 
  
  She determined the B-form of the DNA helix and the location of phosphate groups on the outside of the structure.
- 
  
  Created the dideoxy method of sequencing DNA.
- 
  
  He is most famous for finding out how cells in C. elegans divide.
