Explanation:
Detailed explanation-1: -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-2: -In Watson and Crick’s model, the two strands of the DNA double helix are held together by hydrogen bonds between nitrogenous bases on opposite strands. Each pair of bases lies flat, forming a “rung” on the ladder of the DNA molecule. Base pairs aren’t made up of just any combination of bases.
Detailed explanation-3: -James Watson and Francis Crick with their DNA model at the Cavendish Laboratories in 1953.
