Web25 aug. 2024 · The sugar present in DNA and RNA is mainly pentose sugar. There are mainly two bases of nucleic acids. These are DNA and RNA. The pentose sugars that are present in DNA are deoxyribose. And RNA has ribose sugar, which is a pentose sugar. Ribose sugar is one more –OH group than deoxyribose. WebThe 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.

Web20 jan. 2024 · RNA and DNA have two different sugars: deoxyribose and ribose. The sugars in DNA are adenine, cytosine, guanine, uracil, and phosphate. The sugars in DNA and RNA are similar, but the strands of RNA differ in their chemistry. RNA is longer than DNA and has a higher hydroxyl group, while DNA is shorter and lacks a hydrogen atom. WebRNA has a hydroxyl functional group at that 2' position of the pentose sugar; the sugar is called ribose, hence the name ribo nucleic acid. By contrast, DNA lacks the hydroxyl … fps tecsoft
