Ribonucleic Acid (RNA) Fact Sheet - National Human Genome …
2024年5月24日 · Ribonucleic acid (RNA) is an essential molecule that performs many roles in the cell, from carrying the instructions to make proteins to regulating genes. Ribonucleic acid, shortened to RNA, is one of the most versatile molecules of life.
RNA - Wikipedia
Cellular organisms use messenger RNA (mRNA) to convey genetic information (using the nitrogenous bases of guanine, uracil, adenine, and cytosine, denoted by the letters G, U, A, and C) that directs synthesis of specific proteins. Many viruses encode their genetic information using an RNA genome.

3 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.
