Which of the following is not true of topoisomerase inhibitors?
A. They are effective against cancer cells and are currently used in chemotherapies against colorectal and ovarian cancer. B. They are effective against bacterial infections such as infections by the bacteria that cause anthrax. C. They are highly specific so there is negligible general toxicity and usually no unpleasant side effects associated with anticancer therapies that target topoisomerases. D. The anticancer agents that target topoisomerases generally increase the levels of DNA damage in targeted, rapidly growing tumor cells. E. They inhibit topoisomerases by trapping the topoisomerase-DNA complex in which the DNA is normally cleaved, preventing religation.
