Chapter 8 By Ryan tariche
Watson & Crick
Watson and Crick discovers the double-helix structure of DNA in 1952. They suggested in the summer of 1952 that DNA was made of 2 chains of nucleotide, each in a helix with one going up and one going down. They showed that each strand of DNA molecule was a template for the other and during cell division the 2 strands separate and a new other half is built just like the one before so DNA can reproduce itself without changing its structure.
