Definition: RNA is a molecule found in the nucleus and cytoplasm of cells. It plays an important role in protein synthesis and other chemical activities of the cell. The structure of RNA is similar to that of DNA.

There are several classes of RNA molecules, including messenger RNA, transfer RNA, ribosomal RNA, and other small RNAs, each serving a different purpose.


- RNA interference (RNAi)
- RNA editing
- RNA-binding proteins
- non-coding RNAs
- small RNAs
