Explanation:
Detailed explanation-1: -Watson and Crick (1953) proposed DNA double helix model and won the Nobel Prize; their model of DNA was based on. (i) X-ray diffraction studies of DNA done by Wilkins and Franklin.
Detailed explanation-2: -Answer: Watson and Crick defined DNA as a double helix with two long helical strands twisted together in their paper titled A Structure of Deoxyribose Nucleic Acid. According to them, each DNA strand has discrete units known as bases. The bases along one DNA strand match the bases along the other DNA strand.
Detailed explanation-3: -The double helix describes the appearance of double-stranded DNA, which is composed of two linear strands that run opposite to each other, or anti-parallel, and twist together.
