Regulating genes: an interactive genetic mutation game
From NOVA, this is an online game that lets you introduce mutations to the genetic code of a bug, and see the results. The game highlights why different cells express different genes, and how different mutations affect gene expression differently. Includes background information, a lesson plan (under teacher resources) and a student worksheet (under student resources). Be aware that an audio recording of an article titled "sexual canibilism" (about spiders) is highlighted in the sidebar of this page.
