WebApr 4, 2024 · It consists of adenine, ribose, and a triphosphate moiety. Adenosine is attached by the 9-nitrogen atom to the 1-carbon atom of ribose which in turn is attached at the 5-carbon atom of sugar to a triphosphate group. Three phosphate groups form a triphosphate moiety. They are termed alpha (α), beta (β), and gamma (γ) phosphate groups. WebApr 13, 2024 · 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). In RNA, the base uracil (U) takes the place of thymine.

WebApr 13, 2024 · Definition. …. Ribonucleic acid (abbreviated RNA) is a nucleic acid present in all living cells that has structural similarities to DNA. Unlike DNA, however, RNA is most often single-stranded. An RNA molecule has a backbone made of alternating phosphate groups and the sugar ribose, rather than the deoxyribose found in DNA. WebBoth DNA and RNA are polynucleotides that are linked together by phosphodiester bonds between the ribose moiety of the nucleotides. This creates a “ribose-phosphate” backbone and a 5′-end that is phosphorylated; the 3′-end has a free 3′-hydroxyl ( Fig. 2-17 ). • WebMar 30, 2024 · Hon Cheung Lee, Hon Cheung Lee. Abstract .
