Ribose of dna
Webb6 maj 2010 · DNA contains deoxyribose as the sugar component and RNA contains the sugar ribose. Polynucleotides are formed by covalent linkages between the phosphate of one nucleotide and the sugar of another, resulting in phosphodiester linkages. WebbIn the case of RNA, the five-carbon sugar is ribose, not deoxyribose. Ribose has a hydroxyl group at the 2′ carbon, unlike deoxyribose, which has only a hydrogen atom .

WebbUnlike DNA, RNA in biological cells is predominantly a single-stranded molecule. While DNA contains deoxyribose, RNA contains ribose, characterised by the presence of the 2′-hydroxyl group on the pentose ring (Figure 5). This hydroxyl group make RNA less stable than DNA because it is more susceptible to hydrolysis. Webb6 maj 2010 · DNA contains deoxyribose as the sugar component and RNA contains the sugar ribose.
