Question

A mutation occurs in an operon that prevents the transcription factor from binding to its recognition site on the DNA. In which type(s) of gene regulation would this mutation result in constitutive expression of the structural gene?

Answer 1

Step-by-step explanation:

In the negative inducible and negative repressible regulations of gene.

Answer 2

Answer:Negative inducible and Negative Repressible

Step-by-step explanation:

Negative control of operon includes Negative inducible and Negative repressible both prevent transcription, but are different in there mode of operation.

Negative inducible operon: This is usually a process by which an active repressor regulatory protein binds to the DNA thereby inhibiting RNA polymerase from transcribing gene.

Negative repressible operons: This is also a process when an negative inducer binds to the operator to which prevent DNA transcription
