The names and structures of the major ribonucleotides and one of the deoxyribonucleotides are given in Figure \(\PageIndex{2}\). Figure \(\PageIndex{2}\) The Pyrimidine and Purine Nucleotides. Apart from being the monomer units of DNA and RNA, the nucleotides and some of their derivatives have other functions as well.

Nucleotides are chemical compounds that form the basic structure of nucleic acids like RNA and DNA. The chemical structure of nucleotides is almost the same regardless of whether or not the nucleotide is an RNA or DNA nucleotide. Nucleotides are made out of elements like nitrogen and carbon with a nitrogenous base, a five-carbon sugar component, and a group of phosphates.

ADVERTISEMENTS: In this article we will discuss about the meaning and functions of Nucleotides. Meaning of Nucleotides: Nucleotides are basic units of nucleic acids. They also form energy carriers. Certain nucleotides act as coenzymes. Some nucleotides function as chemical messengers. A nucleotide is a condensation product of three chemicals— a pentose sugar, phosphoric acid and […]

Ribonucleic acids, also called RNA, perform multiple important roles in living cells. RNA is needed for protein synthesis and DNA replication. RNA containing molecules also contribute to the regulation of gene expression and function as enzymes. Like DNA, RNA polymers are make up of chains of nucleotides. These nucleotides have three parts: 1) a five carbon ribose sugar, 2) a
