Detailed explanation-1: -Nucleic acids are naturally occurring chemical compounds that serve as the primary information-carrying molecules in cells. They play an especially important role in directing protein synthesis. The two main classes of nucleic acids are deoxyribonucleic acid (DNA) and ribonucleic acid (RNA).

Detailed explanation-2: -RNA is called nucleic acids because the phosphate group attached to it is acidic in nature. The phosphate group is negatively charged and it donates protons in solution which is an ability possessed by all acids.

Detailed explanation-3: -All nucleic acids are made up of the same building blocks (monomers). Chemists call the monomers “nucleotides.” The five pieces are uracil, cytosine, thymine, adenine, and guanine. No matter what science class you are in, you will always hear about ATCG when looking at DNA. Uracil is only found in RNA.
