Answer:

Explanation:

Operator region are region of DNA (deoxyribonucliec acid) that repressors protein binds to prevent transcription.

Repressor is an example of regulatory protein they regulate the rate at which transcription of operon occurs . A repressor functions when its bounded to the operator and it prevent enzyme RNA (ribonucliec acid)polymerase from moving to DNA to transcribe the nitrogenous bases by placing a complementary base pair.

Activators are other regulatory proteins that bounds to its DNA binding site and increases transcription of the operon.

Answer:

In the mentioned case, both the cells will start to perform replication of their DNA. In the case of G0, that is, the stationary phase, the mammalian cell can pass the restriction point with the supplementation of extracellular proliferation signal. While in the case of G1, which actually does not require any kind of external proliferation signal, as once the cell is in G1 phase, it is ready to go get the next phase. However, both the mammalian cells will cease or halt at G2 checkpoint.
