Question

"Apo-repressor of trp operon is an inactive form of repressor." Justify this statement.Select one of the options below as your answer:
A. Apo-repressor can only bind to the operator site of trp operon when a tryptophan molecule, which is a co-repressor, binds to it.
B. Apo-repressor acts as an inducer if there is a lesser amount of tryptophan present in the surrounding medium and remains inactive when sufficient tryptophan is present.
C. Apo-repressor cannot bind to the operator site of trp operon if a tryptophan molecule, which is a co- repressor, binds to it.

Answer 1

Is it a?

u ready to work out this wid me?

@abbie repressor is the molecule which does not allow a gene to express and binds at the operator site. so it can never acta as an inducer...
