Learn how cells protect against viruses using RNA interference in this video from NOVA’s RNA Lab. All cellular life is in an ancient and unending war with viruses. RNA intereference (RNAi) is one of the ways that cells fight back. Animations show how viruses attack cells, how RNAi works, and how scientists may be able to harness the power of RNAi.
