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.


Last Updated on January 12, 2020 by Sagar Aryal. Nucleic Acids- Nucleosides and Nucleotides. Nucleotide is any member of the class of organic compounds in which the molecular structure comprises a nitrogen-containing unit (base) linked to a sugar and a phosphate group.


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 […]


The four types of nucleotides found in DNA are guanine, cytosine, adenine and thymine. These are nitrogenous bases and are subdivided into purines and pyrimidines. The purines are adenine and guanine, and the pyrimidines are cytosine and thymine.T...


Nucleotide are the basic units of DNA molecule. Our Genetic Material Deoxyribonuclei acid(DNA) are made up of sub-units called monomers. In DNA, the monomers are called nucleotides,and these are linked together to form a polynucleotide chain that ...


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

The Nucleotide database is a collection of sequences from several sources, including GenBank, RefSeq, TPA and PDB. Genome, gene and transcript sequence data provide the foundation for biomedical research and discovery.


Enter organism common name, binomial, or tax id. Only 20 top taxa will be shown. [?] Start typing in the text box, then select your taxid. Use the "plus" button to add another organism or group, and the "exclude" checkbox to narrow the subset. The search will be restricted to the sequences in the database that correspond to your subset.
