Key points: The lac operon of E. coli contains genes involved in lactose metabolism. It's expressed only when lactose is present and glucose is absent. Two regulators turn the operon "on" and "off" in response to lactose and glucose levels: the lac repressor and catabolite activator protein (CAP). The lac repressor acts as a lactose sensor.AP BIO = Regulation of Gene Expression. Get a hint. Trytophan. Click the card to flip 👆. An amino acid that is synthesized by enzymes produced by E.coli.

Steps of the PCR Process. Denaturation (96°C): Heat the reaction strongly to separate, or denature, the DNA strands. This provides single-stranded DNA templates for the next step. Annealing (55 - 65°C): Cool the reaction so the primers can bind to their complementary sequences on the single-stranded template DNA. AP Biology Operon Definitions.

Transcription factors are proteins that help turn specific genes "on" or "off" by binding to nearby DNA. Transcription factors that are activators boost a gene's transcription. Repressors decrease transcription. Groups of transcription factor binding sites called enhancers and silencers can turn a gene on/off in specific parts of the body.
