Chapter 16 - Regulation of Gene Expression - 16.1 - Prokaryotic Gene Expression Is Regulated in Operons - 16.1 Recap - Learning Outcomes - Page 341: 1

In the process of negative regulation, a repressor protein attaches to an operator to block a specific gene expression. For positive regulation, a transcription factor is necessary to bind at the promoter site to allow RNA polymerase to begin transcription.
