In regulation by repression Multiple Choice an amino acid activates the repressor so that the repressor binds to the operator an
Artyom0805 [142]

Answer:

An amino acid activates the repressor so that the repressor binds to the operator and prevents transcription.

Explanation:

In an operon, promoter is followed by operator which is finally followed by the structural genes to be transcribed. RNA Polymerase binds to the promoter and initiates transcription. A repressor can negatively control the transcription process by binding to the operator so that the RNA Polymerase is not able to move forward and transcription is halted.

For example: in trp operon, tryptophan amino acid binds to the repressor molecule which leads to change in repressor's shape. The repressor is now able to bind to the operator and prevent transcription.
