Select the researchers that are correctly matched with their discovery.
A) Pauling provided information on secondary structure in biological molecules.
B) Franklin suggested that DNA was a helix with more than one strand and that there were about 10 bases per turn of the DNA.
C) Watson and Crick collected a large amount of X-ray data on the structure of DNA.
D) Chargaff demonstrated that the adenine and thymine bases and the cytosine and guanine bases interacted in some manner.

Question

Quizplus · Accepted Answer

A: Pauling's work on protein structures led to the discovery of the alpha helix and beta sheet structures.
B: Franklin's X-ray crystallography images were crucial in determining the double-helix structure of DNA.
D: Chargaff's research showed that the amount of adenine was always equal to thymine and the amount of cytosine was always equal to guanine in DNA, which later led to the discovery of base pairing. Watson and Crick built their model of DNA structure based on this knowledge.
