Chapter 9, Problem 15PDQ
Summary Introduction
To review:
The evidence Watson and Crick have at the time of disposal in 1953.
Introduction:
In 1953, Watson and Crick have the breakthrough in finding the DNA. They discovered the double helix structure of DNA. Before this discovery, there are many scientists who worked in this field. This becomes the base evidence for the discovery of Watson and Crick.
