Detailed explanation-1: -The Nobel Prize in Physiology or Medicine in 1962 was awarded to James Watson, Francis Crick and Maurice Wilkins for their discovery of the molecular structure of DNA, which helped solve one of the most important of all biological riddles.
Detailed explanation-2: -Watson and Crick were not the discoverers of DNA, but rather the first scientists to formulate an accurate description of this molecule’s complex, double-helical structure.
Detailed explanation-3: -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-4: -The molecule now known as DNA was first identified in the 1860s by a Swiss chemist called Johann Friedrich Miescher. Johann set out to research the key components of white blood cells?, part of our body’s immune system. The main source of these cells? was pus-coated bandages collected from a nearby medical clinic.
