Why is malignant cell growth considered "uncontrolled?"
A. Cancer cells always divide more rapidly than do normal cells.
B. The mitosis of malignant cells usually produces more than two daughter cells.
C. Malignant cells are able to bypass one or more phases of the cell cycle during cell division.
D. Malignant cells re-enter the cell cycle more frequently, making cell division a continuous process.
D
Although some malignant cells divide very rapidly, this is not true for all malignant cells. Ma-lignant cells have bypassed the normal control mechanisms that restrict entering the cell cycle. Thus, malignant cells re-enter the cell cycle as soon as they finish a round of cell division. Thus, cancer cell division is relentless.
