A control variable is any factor that is controlled or held constant during an experiment. For this reason, it's also known as a controlled variable or a constant variable. A single experiment may contain many control variables.

Suppose an experimenter becomes proficient with a technique that allows her to move DNA sequences within a prokaryotic genome.

Vladimir [108]

Answer:

D) The structural genes will be transcribed continuously.

Explanation:

Suppose an experimenter becomes proficient with a technique that allows her to move DNA sequences within a prokaryotic genome. If she moves the operator to the far end of the operon, past the transacetylase (lacA) gene, the structural genes will be transcribed continuously.

A structural gene is a gene that codes for any RNA or protein product other than a regulatory factor (i.e. regulatory protein).
