RNA - Wikipedia
Ribonucleic acid (RNA) is a polymeric molecule that is essential for most biological functions, either by performing the function itself (non-coding RNA) or by forming a template for the production of proteins (messenger RNA). RNA and deoxyribonucleic acid (DNA) are nucleic acids.

6 天之前 · Ribonucleic acid (abbreviated RNA) is a nucleic acid present in all living cells that has structural similarities to DNA. Unlike DNA, however, RNA is most often single-stranded. An RNA molecule has a backbone made of alternating phosphate groups and the sugar ribose, rather than the deoxyribose found in DNA.

4 天之前 · RNA, complex compound of high molecular weight that functions in cellular protein synthesis and replaces DNA as a carrier of genetic codes in some viruses. RNA consists of ribose nucleotides and the nitrogenous bases adenine, guanine, cytosine, and uracil. Learn about the structure, types, and functions of RNA.
RNA: Properties, Structure, Composition, Types, Functions
2023年8月3日 · RNA (Ribonucleic acid) is a single-stranded nucleic acid molecule and made up of ribonucleotides. A ribose nucleotide in the chain of RNA consists of a ribose sugar, phosphate group, and a base. In each ribose sugar, one of the four bases is added: Adenine (A), Guanine (G), Cytosine (C), and Uracil (U). The base is attached to a ribose sugar ...
