AND ANSWERS
◉ Regulatory proteins bind to _____.
the operator
the lactose-utilization genes
the regulatory gene
RNA polymerase
transcription factors.
Answer: the operator
Transcription is inhibited when a regulatory protein binds to the lac
operon operator.
◉ In the presence of a regulatory protein the lac operon is _____.
transcribed
not transcribed
,transcribed at a faster than usual rate
is turned on
either transcribed or not transcribed.
Answer: not transcribed
The regulatory protein of the lac operon is a repressor.
◉ Which of these is a regulatory gene?.
Answer: D .
