Today’s Plan: 2/16/11 Bellwork: Talk about yesterday and the test (30 mins) Casting gels for tomorrow (30 mins) DNA Tech Notes (the rest of class)
Chapter 13 Regulation of Gene Activity. Humans and nemotodes have about the same number of genes roughly 20,500 So how can a complex organism produce.
Regulation and Gene Expression. Bacteria vs. Eukaryotes Both alter their patterns of gene expression in response to changes in environmental conditions.
REVIEW SESSION
Control of Transcription DNA has “on” and “off” switches Activator –protein that binds near gene’s promoter region - allows RNA polymerase to transcribe.
Controlling Gene Expression. Control Mechanisms Determine when to make more proteins and when to stop making more Cell has mechanisms to control transcription.
2.2 Biological Molecules
Chapters 15 & 16
Gene Control
Regulation of Gene Expression
