WebJan 22, 2024 · In both DNA and RNA molecules, monomers are joined together by phosphodiester bonds that form between the 3’ carbon of one molecule and the 5’ carbon of the next. Number of Nitrogenous Bases. DNA and RNA molecules both contain four nitrogenous bases. Three of these (adenine, cytosine, and guanine) are found in both … Both RNA and DNA contain two major purine bases, adenine (A) and guanine (G), and two major pyrimidines. In both DNA and RNA, one of the pyrimidines is cytosine (C). However, DNA and RNA differ in the second major pyrimidine. DNA contains thymine (T) while RNA contains uracil (U). See more In biochemistry, a ribonucleotide is a nucleotide containing ribose as its pentose component. It is considered a molecular precursor of nucleic acids.
