WebRibonucleic acid (RNA) has a slightly different sugar, known as ribose. Both are made of combinations of four nucleotides, which are special “building block” molecules with a nitrogen base. DNA is composed of long strands … WebJan 24, 2024 · In RNA, the sugar is ribose. Both ribose and deoxyribose are 5-carbon sugars. The carbons are numbered sequentially, to help keep track of where groups are attached. The only difference between them is that 2'-deoxyribose has one less oxygen atom attached to the second carbon.

Factors … WebLike DNA, RNA is made up of nucleotide consisting of a 5-carbon sugar ribose, a phosphate group, and a nitrogenous base. However, there are three main differences between DNA and RNA: RNA uses the sugar ribose instead of deoxyribose. RNA is generally single-stranded instead of double-stranded. RNA contains uracil in place of thymine. WebSummary of Differences Between DNA and RNA. Pentose sugar in the nucleotide of DNA is deoxyribose whereas in the nucleotide of RNA it is ribose.
