Altering patterns of gene expression in prokaryotes would most likely serve the organism\'s survival in which of the following ways?
continuous transcription of the structural gene controlled by that regulator.
does not result in the production of enzymes.
Inducer
Promoter
the cyclic AMP levels are low.
allowing the organism to adjust to changes in environmental conditions
RNA polymerase must bind to the promoter, and the repressor must be inactive.
Repressor
Transcription of the structural genes in an inducible operon
continuous transcription of the structural gene controlled by that regulator.
does not result in the production of enzymes.
Inducer
Promoter
the cyclic AMP levels are low.
allowing the organism to adjust to changes in environmental conditions
RNA polymerase must bind to the promoter, and the repressor must be inactive.
Repressor
A mutation that inactivates the regulatory gene of a repressible operon in an E. coli cell would result in
continuous transcription of the structural gene controlled by that regulator.
does not result in the production of enzymes.
Inducer
Promoter
the cyclic AMP levels are low.
allowing the organism to adjust to changes in environmental conditions
RNA polymerase must bind to the promoter, and the repressor must be inactive.
Repressor
A lack of this nonprotein molecule would result in the inability of the cell to \
continuous transcription of the structural gene controlled by that regulator.
does not result in the production of enzymes.
Inducer
Promoter
the cyclic AMP levels are low.
allowing the organism to adjust to changes in environmental conditions
RNA polymerase must bind to the promoter, and the repressor must be inactive.
Repressor
The lactose operon is likely to be transcribed when
continuous transcription of the structural gene controlled by that regulator.
does not result in the production of enzymes.
Inducer
Promoter
the cyclic AMP levels are low.
allowing the organism to adjust to changes in environmental conditions
RNA polymerase must bind to the promoter, and the repressor must be inactive.
Repressor
When this is taken up by the cell, it binds to the repressor so that the repressor no longer binds to the operator:
continuous transcription of the structural gene controlled by that regulator.
does not result in the production of enzymes.
Inducer
Promoter
the cyclic AMP levels are low.
allowing the organism to adjust to changes in environmental conditions
RNA polymerase must bind to the promoter, and the repressor must be inactive.
Repressor
For a repressible operon to be transcribed, which of the following must occur?
continuous transcription of the structural gene controlled by that regulator.
does not result in the production of enzymes.
Inducer
Promoter
the cyclic AMP levels are low.
allowing the organism to adjust to changes in environmental conditions
RNA polymerase must bind to the promoter, and the repressor must be inactive.
Repressor
A mutation in this section of DNA could influence the binding of RNA polymerase to the DNA:
continuous transcription of the structural gene controlled by that regulator.
does not result in the production of enzymes.
Inducer
Promoter
the cyclic AMP levels are low.
allowing the organism to adjust to changes in environmental conditions
RNA polymerase must bind to the promoter, and the repressor must be inactive.
