rna 是什么意思

中文翻译与英英解释

RNA =ribonucleic acid 【生物化学】核糖核酸。
Ribonucleic acid (RNA) is a ubiquitous family of large biological molecules that perform multiple vital roles in the coding, decoding, regulation, and expression of genes. Together with DNA, RNA comprises the nucleic acids, which, along with proteins, constitute the three major macromolecules essential for all known forms of life.
