RNA Full Form, What is RNA?

RNA full form Ribonucleic Acid

RNA is a nucleic acid, similar to DNA but single stranded. RNA stands for Ribo Nucleic Acid, DNA stands for Deoxyribo Nucleic Acid. The ‘ribo’ section of the name is describing the type of sugar in the nucleic acid backbone.

There are many types of RNA, the three main types carry out very important functions in the cell, all to do with translating the DNA code into functioning proteins. mRNA (messenger RNA) is copy of a DNA sequence (gene) that leaves the cell’s nucleus. The sequence in the mRNA is transcribed into a polypeptide (unprocessed protein) by a ribosome. Ribosomes are made of rRNA (ribosomal RNA). The amino acids used to make the polypeptide are attached to tRNAs (transfer RNAs). Transfer RNAs match with their complement bases on the mRNA, and make sure the correct amino acid is transferred to the polypeptide the ribosome is building.

Like DNA, RNA is assembled as a chain of nucleotides, but unlike DNA it is more often found in nature as a single-strand folded onto itself, rather than a paired double-strand.
