Hello.
The subatomic particles located inside of the nucleus of an atom consist of protons and neutrons.
True. i think i don’t know for sure
The presence of a mutant lac repressor that could not bind lactose would result in no transcription even when lactose was present because the mutant repressor would remain bound to the lac operator
The transcription of lac operator is controlled by the lac repressor. When lactose is present, the lac repressor normally will bind to the lactose, removing itself from the lac operator so it could be transcripted.
In this case, the mutation makes the lac repressor keep binding to the lac operator so the result would be no transcription even when lactose present.
Plants are NOT heterotrophs. Heterotrophs are organisms that cannot produce their own food; generally these are animals.
