Detailed explanation-1: -The best answer choice is 2-both structures contain nucleotides, that form base pairs with other nucleotides, which allows each molecule to act as a template in the synthesis of other nucleic acid molecules. As shown in the image below, DNA and RNA are composed of nucleotides that are similar in structure.
Detailed explanation-2: -One of the most significant similarities between DNA and RNA is that they both have a phosphate backbone to which the bases attach. Because of the phosphate group, this backbone is negatively charged-a quality many genetic techniques appreciate and exploit.
Detailed explanation-3: -Hence, Adenine, Guanine, and Cytosine are common to both DNA and RNA.
Detailed explanation-4: -While both DNA and RNA have sugar molecules in their subunits, those sugars are slightly different. DNA uses deoxyribose, but RNA uses ribose, which has an extra hydroxyl group (OH−) tacked on. DNA and RNA also have nearly identical nitrogenous bases. Both have the bases adenine, cytosine, and guanine.
