10 Questions
What is the role of a repressor protein in gene regulation?
It binds to an operator to prevent gene expression
What is required for positive regulation to initiate transcription?
Transcription factor binding at the promoter
What regulates a gene in inducible regulation?
Presence of its substrate
How are genes coding for proteins in the same pathway controlled?
As a single unit transcribed into a polycistronic mRNA
What type of regulation is the lac Operon an example of?
Negative inducible
What is the primary function of a repressor protein in gene regulation?
To bind to an operator and prevent gene expression
Which type of gene regulation is exemplified by the lac Operon?
Negative Inducible
What is the role of a transcription factor in positive regulation?
To bind at the promoter and enable RNA polymerase to initiate transcription
In which type of regulation is gene expression controlled by the product of its enzyme pathway?
Repressible Regulation
What is the outcome of genes coding for proteins in the same pathway being controlled as a single unit and transcribed into a polycistronic mRNA?
Simultaneous expression of multiple proteins involved in the same pathway
