Which of the following is a correct matching of the researcher with their discovery?
A) Pauling provided information on primary 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 cytosine bases and the uracil and guanine bases interacted in some manner.

Question

Quizplus · Accepted Answer

Franklin's discovery about the helical shape and multiple strands of DNA, as well as the number of bases per turn, was a crucial component for Watson and Crick's ultimate model of the structure of DNA.

The other choices are not accurate matches of the researchers with their discoveries. Pauling focused on the primary structure of molecules such as the sequence of amino acids in proteins, not DNA. Watson and Crick used X-ray data from Franklin and others to propose the double helix structure of DNA. Chargaff discovered that the amount of adenine in DNA is always equal to the amount of thymine, and the amount of cytosine is always equal to the amount of guanine, which became known as Chargaff's rules.
