RNA Interference (RNAi)

Learn about RNA interference (RNAi); a mechanism that inhibits or activates gene expression at the stage of translation or by hindering the transcription of specific genes. Includes animations, learning activities, labs, and research articles. There are links to eThemes Resources on Genetics: Basics, Genetics: Genes and DNA, Genetics: Genetic Disorders, Genetics: Ethics of Genetic Engineering, Genetics: Blood Types, Genetics: Punnett Squares, Genetics: Heredity, and Genetics: Inherited Blood Diseases.
