This document is a report on the lac operon and trp operon in bacteria. It introduces operons as genetic units that control coordinated gene expression. The structure and function of the lac operon is described, including its promoter, operator, repressor gene, and inducer. The structure of the trp operon is also outlined, along with its repressor, leader RNA sequence, leader peptide sequence, and attenuator. The conclusion discusses how the lac operon has been important for studying genetic regulation and how understanding it could provide insights into more complex systems. The conclusion for the trp operon discusses how attenuation allows for synchronization of transcription and translation.
