Who proposed the double-helix model of DNA in 1953 using X-ray diffraction data from Wilkins and Franklin?
A{'text': 'Watson and Crick', 'label': 'A'}
B{'text': 'Avery and MacLeod', 'label': 'B'}
C{'text': 'Hershey and Chase', 'label': 'C'}
D{'text': 'Meselson and Stahl', 'label': 'D'}
Answer & Solution
Correct answer: A. {'text': 'Watson and Crick', 'label': 'A'}
Watson and Crick proposed the double-helix model in 1953, building on X-ray diffraction images produced by Maurice Wilkins and Rosalind Franklin and on Chargaff's base-ratio rule.
