Lac Operon - gene regulation in prokaryotes
This lecture explains the lac operon and the regulation of gene expression in prokaryotes by lac operon. The lac operon consists of three structural genes, and a promoter, a terminator, regulator, and an operator. The three structural genes are: lacZ, lacY, and lacA. lacZ encodes β-galactosidase (LacZ), an intracellular enzyme that cleaves the disaccharide lactose into glucose and galactose.
This video lecture will teach you the mechanism of lac operon. It will also explain the positive and negative regulation of Lac operon and how it is controlled in response to the presence of Glucose. This video will also help you to realize the difference between a catabolic and an anabolic operon.

Became a fan of you after watching this video. Great explanation. Thanks a lot. Wished you were my biology teacher.
This video has very good production quality. Not that it matters to me nor is it possible for a busy person such as yourself to make all your videos in such a manner. But you can see that you got more thumbs up in this video. Clean white board as the background with you teaching. Keep it up and as always, you're the best at what you do!
You explain it better than my professor. The text book is even confusing. Thank you for your videos.
