1. The Proteins and RNAs of Gene Regulation

RNA Polymerase Binds to DNA at Promoters

Transcription Initiation Is Regulated by Proteins and RNAs

Many Bacterial Genes Are Clustered and Regulated in Operons

The lac Operon Is Subject to Negative Regulation

Regulatory Proteins Have Discrete DNA-Binding Domains

Regulatory Proteins Also Have Protein-Protein Interaction Domains
