Explanation:
Detailed explanation-1: -In “A Structure of Deoxyribose Nucleic Acid, ‘’ Watson and Crick described DNA as a double helix that contained two long, helical strands wound together. In their model, each DNA strand contained individual units called bases, and the bases along one DNA strand matched the bases along the other DNA strand.
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.
