Deoxyribose - Wikipedia
WEBDeoxyribose, or more precisely 2-deoxyribose, is a monosaccharide with idealized formula H− (C=O)− (CH 2 )− (CHOH) 3 −H. Its name indicates that it is a deoxy sugar, meaning that it is derived from the sugar ribose by loss of a hydroxy group.
Deoxyribose | DNA, Nucleic Acids, Sugars | Britannica
WEBdeoxyribose, five-carbon sugar component of DNA (q.v.; deoxyribonucleic acid), where it alternates with phosphate groups to form the “backbone” of the DNA polymer and binds to nitrogenous bases. The presence of deoxyribose instead of ribose is one difference between DNA and RNA (ribonucleic acid).
Deoxyribose - Definition and Structure | Biology Dictionary
WEBApr 28, 2017 · Deoxyribose is the five-carbon sugar molecule that helps form the phosphate backbone of DNA molecules. DNA, or deoxyribonucleic acid is a polymer formed of many nucleic acids. Each nucleic acid is composed of a deoxyribose molecule bound to both a phosphate group and either a purine or a pyrimidine. Purines have two carbon …

Discovery of the structure of DNA (article) | Khan Academy
WEBThe components of DNA. From the work of biochemist Phoebus Levene and others, scientists in Watson and Crick's time knew that DNA was composed of subunits called nucleotides 1 . A nucleotide is made up of a sugar (deoxyribose), a phosphate group, and one of four nitrogenous bases: adenine (A), thymine (T), guanine (G) or cytosine (C).
Molecular structure of DNA (video) | Khan Academy
WEBAbout. Transcript. DNA, short for deoxyribonucleic acid, consists of nucleotides forming a double helix structure. Nucleotides contain a phosphate group, deoxyribose sugar, and a nitrogenous base. The bases, adenine, thymine, cytosine, and guanine, pair up through hydrogen bonds, creating the rungs of the DNA ladder. Created by Sal Khan. Questions.
10.2: Structure and Function of DNA - Biology LibreTexts
WEBApr 21, 2024 · Key Concepts and Summary. Nucleic acids are composed of nucleotides, each of which contains a pentose sugar, a phosphate group, and a nitrogenous base. Deoxyribonucleotides within DNA contain deoxyribose as the pentose sugar. DNA contains the pyrimidines cytosine and thymine, and the purines adenine and guanine.
9.1 The Structure of DNA - Concepts of Biology | OpenStax
WEBThe 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 . There are four types of nitrogenous bases in DNA.
