RNA

An abbreviation of "RiboNucleic Acid". It constitutes the second type of nucleic acid, the other being DNA. RNA is found in the nucleus of the cell as well as in the cytoplasm. Like DNA, it is also a very long molecule, with a repeated structure, made up of a base, a sugar and a phosphate. But contrary to DNA it is only made up of a single helix. It is synthesized in the cell by recopying DNA and plays an essential role in the synthesis of proteins.
