How are DNA synthesis inhibitors used to fight bioterrorism?

The bacterium Bacillus anthracis, known as anthrax, causes an often fatal disease that is also called anthrax. On November 7, 2001, the Senate Majority Leader's office received an anthrax-tainted letter. More than 30 Senate workers showed signs of exposure. The U. S. Centers for Disease Control and Prevention (CDC) recommends that anyone who might have been exposed to anthrax begin treatment with the antibiotic ciprofloxacin, a DNA-synthesis inhibitor.

Part A

To understand how ciprofloxacin works, it's important to be able to visualize the events of DNA synthesis. To help with this, there is a diagram of a replication bubble, show on it the 5'?3' polarity of the two parental DNA strands, the leading and lagging daughter strands at each replication fork, helicase, and topoisomerase.
