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. 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.The lac Operon. The lac operon is a cluster of genes that code for a series of enzymes that work together to digest lactose into two monosaccharides: glucose and galactose. Here’s how the expression of these structural genes is controlled.
