Control of Gene Expression in Bacteria

Control of Gene Expression in Bacteria. 17. Key Concepts. In bacteria, gene expression can be controlled at three levels: transcription, translation, or post-translation (protein activation). Changes in gene expression allow bacterial cells to respond to environmental changes.

Ch 18 Introduction

Ch 18 Introduction. A cell does not express all of its genes all of the time. Instead, they are very selective about the genes they express, how strongly they are expressed, and when they are expressed.

Regulation of gene and cellular activity

Regulation of gene and cellular activity. Regulating Gene Expression . Cells use different mechanisms to sense and respond to conditions within or outside the cell. Regulatory proteins help a cell sense internal changes and alter its gene expression to match. Figure 10.1A.
