2024年10月17日 · 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.
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.
