Why Do Researchers Often Include DNase in Their Antibiotic Preparations

Why do researchers often include DNase in their antibiotic preparations to eliminate biofilms?

A) Targeting the bacterial chromosome is the most effective way to kill biofilm bacteria.
B) If the microbe's genome can be destroyed, the cell will die.
C) The antibiotics cannot readily penetrate the extracellular debris, which often includes DNA from lysed cells.
D) The antibiotics target the cell wall and the DNase targets the genome, effectively destroying the biofilm.
