In E. coli, lactose binds with:
A. the lactose operon repressor, preventing it
from binding to the operator. This allows the
lacZ and lacY genes to be transcribed.
B. the lactose operon operator, preventing it
from binding to the repressor. This allows the
lacZ and lacY genes to be transcribed.
C. the lactose operon repressor, helping it
bind to the operator. This prevents the lacZ
and lacY genes from being transcribed.
D. the lactose operon operator, preventing
RNA polymerase from being recruited. This
prevents the lacZ and lacY genes from being
transcribed.
E. the lactose operon operator, recruiting
RNA polymerase. This allows the lacZ and
lacY genes to be transcribed.
