1 Lac Operon Tricia Tran, Adriana Mulla-Carrillo Emma Schuler & Katherine Hastings

2 Lac Operon Operon: a unit of genetic function common in bacteria and phages, consisting of coordinately regulated clusters of genes with related functions. Lac Operon is an inducible operon. o It is normally off, but needs an inducer to turn it on. The inducer is allolactose: an isomer of lactose formed in small amounts from lactors that enters the cell. The inducer inactivates the repressor. The presence of lactose inactivates the repressor

Regulation of Gene Expression

Regulation of Gene Expression
 Discovered in the bacterium, E. coli  Used as a model for gene regulation  An operon is a set of genes and the switches that control the expression.
