Answer: Both deoxyribonucleic acid (DNA) and ribonucleic acid (RNA) are made up of nucleotides which consist of three parts: 1  Nitrogenous Base. 2  Purines and pyrimidines are the two categories of nitrogenous bases. 3  Pentose Sugar. 4  In DNA, the sugar is 2'-deoxyribose. 5  Phosphate Group. 6  A single phosphate group is PO 4 3- .
RNA (ribonucleic acid) and DNA (deoxyribonucleic acid) are chemicals called nucleotides that are made by the body. They appear to be essential under conditions of rapid growth such as intestinal development, liver surgery or injury, and also during challenges to the immune system.
