If radioactive nucleotide bases were provided to bacteria during DNA synthesis, then after cell division you would find:
Both bacteria would be equally radioactive.
One bacteria would be radioactive and the other not.
Neither would be radioactive because DNA polymerase can distinguish between isotopes.

Question 8

What is the end result of DNA replication?
Two DNA molecules each both have two new strands.
Two DNA molecules which each have one old strand and one new strand.
Two DNA molecules which each have two new strands and two old strands.
Two DNA molecules one with two old strands and one with two new strands.

Question 9
Select one answer.

During DNA replication, it is possible for the T residue in the template strand to form two hydrogen bonds with a T base on the new strand. This doesn’t normally occur because:
The T-T basepair contains two of the smaller sized bases.
DNA polymerase cannot incorporate T into the newly synthesized strands.
The normal A-T base pairing uses 3 hydrogen bonds, so it will be preferred.
The two T-T hydrogen bonds will be weaker than the two hydrogen bonds between an A-T pair.
