lacI^S encodes superrepressors,repressors that always bind to the operator and prevent gene transcription.

Question

Quizplus · Accepted Answer

The lacI^S region of DNA includes mutations that cause the production of superrepressor LacI proteins, which have a higher affinity for the operator sequence than wild-type LacI proteins. This results in constitutive repression of the lac operon, as the LacI superrepressor always binds to the operator and prevents transcription of the lac genes.
