Description:RNA interference (RNAi) is a mechanism that inhibits gene expression at the stage of translation or by hindering the transcription of specific genes. RNAi targets include RNA from viruses and transposons (probably as a form of innate immune response), and also plays a role in regulating development and genome maintenance. Includes important reviews of the broadest interest to geneticists and their colleagues in affiliated disciplines, providing researchers an overview and synthesis of the latest findings in the area Presents up-to-date research from leaders in the field Praise for Advances in Genetics: "Outstanding both in variety and in the quality of its contributions."--NATURE "Can be highly recommended to geneticists, and biologists in general...will prove to be of high importance for the development of the science of genetics."--SCIENCE
