Gene Regulation

Mr. Anderson explains gene regulation, focusing on how genes are expressed or not. He uses E. coli as an example to introduce the concept, then delves into the mechanisms of gene regulation in bacteria, including the lac and trp operons. He contrasts this with eukaryotic gene regulation, highlighting the role of transcription factors. The video covers both positive and negative control mechanisms, illustrating how organisms efficiently manage gene expression in response to environmental changes.
