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 ...
4 Μαρ 2024 · Definition And Structure. Deoxyribose is a 5- carbon sugar found in DNA. Contains one less oxygen atom than ribose. Structure: Pentose sugar with four carbons and one hydrogen. Function In Dna. Deoxyribose forms the backbone of the DNA molecule. Key Role: Provides structural stability to DNA.
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 9.3). There are four types of nitrogenous bases in DNA. Adenine (A) and guanine (G) are double-ringed purines, and cytosine (C) and thymine (T) are smaller, single-ringed pyrimidines.
12 Δεκ 2014 · RNA carries messages out of the cell nucleus to cytoplasm. The structure of RNA nucleotides is very similar to that of DNA nucleotides, with the main difference being that the ribose sugar backbone in RNA has a hydroxyl (-OH) group that DNA does not. This gives DNA its name: DNA stands for deoxyribonucleic acid.
