Nucleotide - Wikipedia
Nucleotides are organic molecules composed of a nitrogenous base, a pentose sugar and a phosphate. They serve as monomeric units of the nucleic acid polymers – deoxyribonucleic acid (DNA) and ribonucleic acid (RNA), both of which are …
Nucleotide - Definition, Structure (3 Parts), Examples & Function
2019年10月4日 · A nucleotide is an organic molecule that is the building block of DNA and RNA. They also have functions related to cell signaling, metabolism, and enzyme reactions. A nucleotide is made up of three parts: a phosphate group, a 5-carbon sugar, and a nitrogenous base. The four nitrogenous bases in DNA are adenine, cytosine, guanine, and thymine.

2023年8月31日 · What Is a Nucleotide? A nucleotide is an organic molecule that serves as the building block for nucleic acids like DNA (deoxyribonucleic acid) and RNA (ribonucleic acid). These molecules consist of three primary components: a nitrogenous base, a sugar molecule, and one or more phosphate groups.
Nucleotide - National Human Genome Research Institute
2 天之前 · A nucleotide is the basic building block of nucleic acids (RNA and DNA). A nucleotide consists of a sugar molecule (either ribose in RNA or deoxyribose in DNA) attached to a phosphate group and a nitrogen-containing base. The bases used in DNA are adenine (A), cytosine (C), guanine (G) and thymine (T).
Nucleotide: Structure, Examples and Function - BYJU'S
A nucleotide is an organic molecule with a basic composition of a nitrogenous base, pentose sugar and phosphate. DNA and RNA are polynucleotides, which contain a chain of nucleotides monomers with different nitrogenous bases. Nucleotides are essential for carrying out metabolic and physiological activities.
