Deoxyribose - Wikipedia
The DNA (deoxyribonucleic acid) molecule, which is the main repository of genetic information in life, consists of a long chain of deoxyribose-containing units called nucleotides, linked via phosphate groups.
Deoxyribose - Definition and Structure | Biology Dictionary
2017年4月27日 · 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 and nitrogen rings ...
Deoxyribose | DNA, Nucleic Acids, Sugars | Britannica
deoxyribose, 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).
10.2: Structure and Function of DNA - Biology LibreTexts
2024年4月21日 · Deoxyribonucleotides within DNA contain deoxyribose as the pentose sugar. DNA contains the pyrimidines cytosine and thymine, and the purines adenine and guanine. Nucleotides are linked together by phosphodiester bonds between the 5ʹ phosphate group of one nucleotide and the 3ʹ hydroxyl group of another.
Deoxyribose - (Biochemistry) - Vocab, Definition, Explanations
Deoxyribose is a five-carbon sugar that is a crucial component of DNA, where it serves as the backbone that links together nucleotides. This sugar differs from ribose, which is found in RNA, by lacking an oxygen atom at the 2' carbon position, hence the prefix 'deoxy.'.
10.2 Structure and Function of DNA - Microbiology | OpenStax
Nucleotides that compose DNA are called deoxyribonucleotides. The three components of a deoxyribonucleotide are a five-carbon sugar called deoxyribose, a phosphate group, and a nitrogenous base, a nitrogen-containing ring structure that is responsible for complementary base pairing between nucleic acid strands (Figure 10.11). The carbon atoms ...
