Ciprofloxacin inhibits dna gyrase, a bacterial topoisomerase that cuts dna ahead of the replication fork, winds the dna in a direction that relieves the twists added during dna synthesis, and then reseals the dna. in ciprofloxacin-treated bacteria, newly synthesized dna is found in fragments. based on this evidence, what activity of dna gyrase is likely to be inhibited by ciprofloxacin?

Ciprofloxacin inhibits the action of DNA gyrase leading to those fragmented DNAs, which leads to ultimate death of the bacteria.

Explanation:

DNA gyrase is the enzyme which seals the fragments of the DNA.

During the DNA replication, DNA is produced in fragments due to the act of DNA polymerase on the DNA molecule. But as the DNA is produced, it leads to the formation of fragments. This needs to be sealed by the DNA gyrase which is needed to seal the fragments to form the whole circular DNA.

Ciprofloxacin inhibits the action of DNA gyrase leading to those fragmented DNAs, which leads to ultimate death of the bacteria.

the answer is "a.) well–developed vascular system."
