Question- E.coli is a good model organism for studying a wide range of biological reactions. Your research advisor has asked you to design an experiment that will test potential drugs that bind to DNA and to use E.coli for your experiment. If you treat E.coli by suspending them in a solution that is 2.3 µM in drug, what is the ratio of drug molecules-to-DNA bases ([drug]/[DNA bases]) in your study? Assume that the drug easily crosses biological membranes.
I want you to explicate the chemistry in this problem
