Detailed explanation-1: -Correct answer: Nucleic acids are made up of nucleotides that contain a pentose sugar, a phosphate group, and a nitrogenous base. There are two types of nucleic acids; DNA and RNA. The difference between these two nucleic acids is their pentose sugar.
Detailed explanation-2: -Guanidin is not present in nucleic acid and as cytosine, Adenine, Thymine and Guanine are the four main bases found in nucleic acid. Adenine and Guanine are purines while thymine and cytosine are pyrimidines.
Detailed explanation-3: -Nucleic acids are large biomolecules that play essential roles in all cells and viruses. A major function of nucleic acids involves the storage and expression of genomic information. Deoxyribonucleic acid, or DNA, encodes the information cells need to make proteins.
