For an in-detail comprehension of regulation of bacterial transcription, here is our sqadia.com medical video lecture. Initially, transcription initiation, regulation of β-galactosidase and certain regulatory proteins has been conversed about. Subsequently, light has been shed upon the control of both inducible and repressible genes. Moreover, lac operon and lac repressor along with tryptophan and arabinose operons have been delineated.
In this section, primarily induction and repression of enzyme synthesis has been discussed. Following this, regulation of β-galactosidase gene and inducible and repressible enzymes has been shed light upon. Moreover, control of transcription by regulatory proteins and helix-turn-helix DNA-binding domains have been brought under consideration. Conclusively, zinc finger DNA-binding domain along with repressor and activator proteins have been delineated.
Negative and positive control of an inducible gene has been shed light upon. Subsequently, negative and positive control of repressible gene has been elaborated in-detail. In the end, general aspects of regulation, gene expression along with decision making process of E. coli has been conversed about.
Regulation of Operons
Lactose operon (Lac Operon) has primarily been elucidated. Moreover, induction of Lac operon and lac repressor has been talked about. In addition to this, mechanism of Lac operon and catabolite activator protein (CAP) has been comprehensively explained. In the end, the educator has summed up by discussing about the regulation through catabolite activator protein.
Tryptophan and Arabinose Operon
In the beginning, structure and mechanism of tryptophan operon has been elaborated. Moreover, structure and mechanism of arabinose operon has also been comprehensively explained. Towards the end, mechanism of arabinose operon has been delineated.
