27 Απρ 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 and nitrogen rings ...
8 Απρ 2019 · Deoxyribonucleic acid, or DNA, is a biological macromolecule that carries hereditary information in many organisms. DNA is necessary for the production of proteins, the regulation, metabolism, and reproduction of the cell.
24 Σεπ 2018 · The sugars in DNA are 2’-deoxyribose sugars in that the carbon at position 2’ lacks a hydroxyl group and instead has two hydrogen atoms. RNA, which we will consider in a later chapter, is a similar copolymer, but its sugars are ribose sugars, which contain a hydroxyl group at the 2’ position in place of one of the two hydrogen atoms.
Scientists already knew that nucleotides contain the same three important components: a nitrogenous base, a deoxyribose (5-carbon sugar), and a phosphate group (Figure \(\PageIndex{2}\)). The nucleotide is named depending on the nitrogenous base: adenine (A), thymine (T), cytosine (C), and guanine (G).
Diagram the structure of DNA. The building blocks of DNA are nucleotides. The important components of each nucleotide are a nitrogenous base, deoxyribose (5-carbon sugar), and a phosphate group (see Figure 1). Each nucleotide is named depending on its nitrogenous base.
21 Απρ 2024 · Describe the biochemical structure of deoxyribonucleotides. Identify the base pairs used in the synthesis of deoxyribonucleotides. Explain why the double helix of DNA is described as antiparallel. In Microbial Metabolism, we discussed three classes of macromolecules: proteins, lipids, and carbohydrates.
13 Σεπ 2023 · Deoxyribose: It is a five-carbon sugar molecule that forms the backbone of the DNA strands. The deoxyribose sugar molecules are connected through a phosphodiester bond, creating a sugar-phosphate backbone. Phosphate Group: It is attached to the 5’ carbon of the deoxyribose sugar.
