RNA interference (RNAi)is used by many different organisms to regulate the activity of genes. This animation explains how RNAi works and introduces the two main players:
- small interfering RNAs (siRNAs)
- microRNAs (miRNAs)
The Nature video takes you on an audio-visual journey, diving into a cell to show how genes are transcribed to make messenger RNA (mRNA) and how RNAi can silence specific mRNAs to stop them from making proteins.
