Question

Suppose an experimenter becomes proficient with a technique that allows her to move DNA sequences within a prokaryotic genome.If she moves the repressor gene (lacI), along with its promoter, to a position at some several thousand base pairs away from its normal position, we would expect the _____.repressor will no longer bind to the operatorlac operon will be expressed continuouslylac operon will function normallyrepressor will no longer bind to the inducerrepressor will no longer be made

Answer 1

Answer:

The correct option is lac operon will function normally.

Explanation:

The promoter region can be described as a region due to which transcription begins for a certain gene. Promoters can be present near to the gene for which they initiate transcription or they might be present several sequences away upstream.

The promoter region will still be able to initiate transcription several base pairs away hence the lac operon will function normally. The repressor will also detect the promoter and function normally.
