Which investigator(s) studying DNA collected data that could be used to infer the positions of atoms in DNA?
A) Watson and Crick
B) Chargaff
C) Hershey and Chase
D) Avery
E) Franklin

Question

Quizplus · Accepted Answer

Franklin, using X-ray crystallography, obtained diffraction patterns of DNA molecules that provided information on the structure of DNA, including its helical nature and the angle between its nitrogenous bases. This data eventually led to the ability to infer the positions of atoms within the DNA molecule. Watson and Crick used Franklin's data, along with data from other researchers, to construct their proposal of the double helix structure of DNA. Chargaff's work involved analyzing the base composition of DNA, while Hershey and Chase studied bacteriophages to confirm that DNA was the genetic material. Avery's work confirmed that DNA was the genetic material and not protein.
