Multiple Choice
Who created the first widely accepted accurate double-helix model of DNA structure in 1953?
A
Gregor Mendel
B
Thomas Hunt Morgan
C
James Watson and Francis Crick
D
Rosalind Franklin and Maurice Wilkins
Verified step by step guidance1
Understand that the question is about the historical discovery of the DNA double-helix structure, which is a fundamental concept in genetics.
Recall that Gregor Mendel is known as the father of genetics for his work on inheritance patterns in pea plants, not for the DNA structure.
Recognize that Thomas Hunt Morgan contributed to genetics through his work on fruit fly chromosomes, but did not discover the DNA structure.
Identify that Rosalind Franklin and Maurice Wilkins provided critical X-ray diffraction images of DNA that helped reveal its structure, but they did not create the model themselves.
Know that James Watson and Francis Crick are credited with building the first widely accepted accurate double-helix model of DNA in 1953, based on available data including Franklin's images.
