Answer:
the bacterial cell will die since it cannot replicate or transcribe its DNA
Explanation:
DNA is a double stranded molecule that stores genetic information in living cells. However, the DNA needs to be replicated before cell division and also transcribed in order to be expressed.
As stated in this question, DNA helicase is an important enzyme in the replication and transcription of DNA because it is the enzyme responsible for separating the double stranded DNA into single strands before they can be replicated or transcribed.
According to this question, fluoroquinolones such as ciprofloxacin, are synthetic drugs that interfere with the action of DNA helicases in a cell. This means that a cell affected by this synthetic drug will be unable to separate it's DNA and hence, will die since it cannot replicate or transcribe its DNA.
