A Bacterium Inherits a Mutation That Renders Its Topoisomerase Enzyme

Multiple Choice

A bacterium inherits a mutation that renders its topoisomerase enzyme nonfunctional.What phenotype would you expect to see in this bacterium?

A) The cell would accumulate broken DNA because overwinding cannot be corrected,so the cell will be unable to replicate and will die.
B) The cell would accumulate supercoiled DNA,but otherwise it is perfectly normal.
C) The cell would accumulate relaxed DNA,which would make DNA replication and cell division highly disorganized and lead to cell death.
D) The cell would accumulate relaxed DNA,but otherwise it is perfectly normal.
E) The cell would be unaffected because bacteria have many different topoisomerases that are involved in replication.
