Actinomyocin-D was found to be effective in preventing the growth of rapidly dividing tumor cells by blocking DNA replication. Scientists discovered actinomycin-D also caused side effects like hair loss and a decrease in the number of red blood cells. Which statement best explains the reason that actinomycin-D caused the side effects?
A. Actinomyocin-D alters the environment so that hair and red blood cells are killed B. Actinomyocin-D affects all cell division, so healthy cells are also unable to divide C. Actinomyocin-D targets tumor cells, and the side effects are due to the release of chemicals from the tumor cells D. Actinomyocin-D kills the cells that support the hair cells and red blood cells leading to the death of these cells
