Nucleotide - Wikipedia
WEBNucleotides 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 essential biomolecules within all life-forms on Earth.
Single-nucleotide polymorphism - Wikipedia
WEBIn genetics and bioinformatics, a single-nucleotide polymorphism (SNP / snɪp /; plural SNPs / snɪps /) is a germline substitution of a single nucleotide at a specific position in the genome.
3 Parts of a Nucleotide and How They Are Connected - ThoughtCo
WEBAug 13, 2024 · Nucleotides in DNA and RNA. Both DNA and RNA are made up of nucleotides, which consist of three parts: Nitrogenous Base. Purines and pyrimidines are the two categories of nitrogenous bases. Adenine and guanine are purines. Cytosine, thymine, and uracil are pyrimidines.
9.1: The Structure of DNA - Biology LibreTexts
WEBMar 17, 2022 · The building blocks of DNA are nucleotides, which are made up of three parts: a deoxyribose (5-carbon sugar), a phosphate group, and a nitrogenous base (Figure 9.1.2 9.1. 2). There are four types of nitrogenous bases in DNA.
9.1 The Structure of DNA - Concepts of Biology - OpenStax
WEBThe phosphate group of one nucleotide bonds covalently with the sugar molecule of the next nucleotide, and so on, forming a long polymer of nucleotide monomers. The sugar–phosphate groups line up in a “backbone” for each single strand of DNA, and the nucleotide bases stick out from this backbone.
Nucleotide - Definition, Structure (3 Parts), Examples & Function
WEBOct 29, 2016 · 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.
1.1: Nitrogenous bases, Nucleosides and Nucleotides
WEBRecall some basic structural features of the nucleotide building blocks of DNA. A nucleotide is composed of a nitrogenous base, deoxyribose (five-carbon sugar), and at least one phosphate group. The nitrogenous bases are purines such as adenine (A) and guanine (G), or pyrimidines such as cytosine (C), thymine (T), and uracil (U).
