A new

type of

treatment: Some human diseases involve the unregulated growth of cells. Although some patients are not affected by these

growths, many are harmed. Cells in harmful growths divide uncontrollably and can eventually invade other cells, tissues and

organs of the body. Some patients carry a mutation on one or more growth suppressor genes (GSGs). GSGs help to repair

damage to DNA. This mutation decreases an individual’s ability to fight these harmful growths. Recently researchers reported

on the results of using a combination of two types of medicine

to treat patients with unregulated growths caused by a lack of

functioning GSGs. When medicine “X” and “Y” are used

together they cause the cell processes in the targeted cell to fail.

In order for medicine X to produce the effects that the

researchers observed, it must have entered into which part of the

targeted cells?

a. Nucleus b. Endoplasmic reticulum c. golgi apparatus d. Ribosomes
