The option most likely to cause cancer is mutations in regulatory proteins during the cell cycle may cause affected cells to divide uncontrollably. (Option A).
What is cancer?
Cancer is often associated with mutations in genes that control the cell cycle, such as those encoding regulatory proteins. These mutations can lead to uncontrolled cell division and the formation of tumors.
Options B, C, and D describe scenarios that might have adverse effects on cells, but they don't directly address the fundamental issue of uncontrolled cell growth due to mutations in regulatory proteins during the cell cycle.
So option A is the correct answer.
The complete question is below:
Cancer is the uncontrolled growth of cells. Which of the following would be most likely to cause
cancer?
Group of answer choices
A. Mutations in regulatory proteins during the cell cycle may cause affected cells to divide uncontrollably.
B. Cells, which come in contact with cancerous cells, become cancerous themselves.
C. A bacterial infection modifies a cell, causing it to grow out of control.
D. During the synthesis stage, crossing over will cause cells to divide without inhibition
