Question
Operons are clusters of genes that are regulated as a group. They can be
characterized as either repressible or inducible. What is the main difference
between the two? *
O An inducible operon is usually off while a repressible operon is usually on.
Binding to a repressor molecule turns repressible operons off and inducible operons
on.
Repressible operons turn off when the repressor is active while inducible operons turn
on when the repressor is active.
Inducible operons require a co-repressor to turn the operon off.
