Regulation of gene Expression | Lac Operon | Biology

The regulation of gene expression Gene regulation is the process of controlling which genes in a cell’s DNA are expressed (used to make a functional product such as a protein). The lac operon • The lac operon of E. coli contains genes involved in lactose metabolism. It’s expressed only when lactose is present and glucose is absent. • Two regulators turn the operon “on” and “off” in response to lactose and glucose levels: the lac repressor and […]

Gene Regulation and the Order of the Operon

Explore gene expression with the Amoeba Sisters, including the fascinating Lac Operon found in bacteria! Learn how genes can be turned “on” and “off” and why this is essential for cellular function. Check out our FREE video handouts on The Amoeba Sisters videos demystify science with humor and relevance. The videos center on Pinky’s certification and experience in teaching biology at the high school level. For more information about The Amoeba Sisters, visit: REFERENCES: We cover the […]
