उत्तर
The DNA double-helix model was given by Watson and Crick.
Explanation:
James Watson and Francis Crick proposed the famous double-helix model of DNA in 1953, utilising crucial X-ray diffraction data gathered by Rosalind Franklin and Maurice Wilkins. Their model revealed that DNA consists of two antiparallel strands twisted around a common axis, held together by complementary base pairing. This groundbreaking structural discovery explained how genetic information is stored and replicated, earning them a Nobel Prize in 1962.
