RNA - Wikipedia
WEBRibonucleic 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).

WEB5 days ago · 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.

WEBOct 14, 2021 · A cell copies DNA’s instructions — a process scientists call transcription — onto a strand of messenger RNA, or mRNA. It’s a good name, because mRNA is a message. Once created, it exits the nucleus, leaving the DNA safe inside. rRNA: Outside a cell’s nucleus, the mRNA binds to what’s known as rRNA.
