Question

Which of the following techniques was most helpful to Watson and Crick in developing their model for the structure of DNA?

A Radioactive labeling
B Electrophoresis
C Cloned DNA
D Transgenic animals
E X-ray crystallography

Answer 1

E. X-ray crystallography was most helpful to Watson and Crick in developing their model for the structure of DNA.

Step-by-step explanation:

X-ray crystallography was most helpful to Watson and Crick in developing their model for the structure of DNA. X-ray crystallography is a technique that involves using X-ray diffraction patterns to determine the atomic and molecular structure of a crystal. Watson and Crick used X-ray crystallography data from Rosalind Franklin and Maurice Wilkins to develop their model for the structure of DNA. They used this data to create a model that showed the structure of DNA as a double helix, which is now known to be the correct structure of DNA.
