Answer:

Explanation:
We know that the AmpR gene region has been interrupted. So this means the AmpR gene will not function in the recombinant DNA.
But the question tells us that the TetR gene is not interrupted, so the TetR gene will still function.
AmpR represses the protein that confers resistance to ampicillin, and AmpR is no longer functional, <u>so the new bacterial cells will be resistant to ampicillin.</u>
TetR represses the protein that causes resistance to tetracyline, and TetR is still functional, <u>so the new bacterial cells will not be resistant to tetracycline. </u>
This means B, there will be <u>growth on ampicillin but not tetracycline containing media.</u>
