Major components of DNA- Deoxyribose sugar, Nitrogen Base, and a Phosphate group.
Chargaff- Discovered that Adenine bonds with Thymine and Guanine bonds Cytosine
Franklin- Took X-rays of DNA
Watson and Crick- Used Frankins X- ray to discover the double helix


Chargaff - Created the rule/order of adenine to thymine and guanine to cytosine

Franklin - Took x-rays of DNA

Watson - Assisted Crick in creating the double helix model

Crick - Assisted Watson in creating the double helix model
