Operon

The video explains the concept of operons, focusing on the lac operon in E. coli and the trp operon. It describes how operons function as gene regulation systems in bacteria, detailing the components like promoter, repressor, operator, and genes. The lac operon is activated in the presence of lactose, while the trp operon is activated in the absence of tryptophan. The video includes a simulation to help visualize these processes.
