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? select one or more: negative inducible negative repressible positive inducible positive repressible

The answer is negative inducible and positive repressible. This is because, since the gene is constitutive, it is always transcribed unless repressed. It is also structural because it codes for enzymes or proteins that are non-regulatory. The fact that transcription factors cannot bind to the promoter means it cannot be transcribed (hence also repressed by the mutation).
