Which of the following is most likely an indication that cells may have become cancerous?
A
Cells responding appropriately to growth-inhibitory signals
B
Stable DNA with few mutations
C
Uncontrolled cell division
D
Normal rates of apoptosis
Verified step by step guidance1
Understand the characteristics of cancerous cells: Cancerous cells are typically characterized by uncontrolled cell division, which means they bypass normal regulatory mechanisms that control cell growth and division.
Review the role of growth-inhibitory signals: Normal cells respond to growth-inhibitory signals to prevent excessive division. If cells ignore these signals, it can lead to uncontrolled growth, a hallmark of cancer.
Examine the importance of DNA stability: Stable DNA with few mutations is a sign of healthy cells. Cancerous cells often have accumulated mutations that disrupt normal cellular functions, including growth regulation.
Consider apoptosis (programmed cell death): Normal rates of apoptosis help maintain tissue health by removing damaged or unnecessary cells. Cancerous cells often evade apoptosis, allowing them to survive and proliferate uncontrollably.
Conclude that uncontrolled cell division is the most likely indication of cancerous cells: This is because it directly reflects the loss of regulatory control over cell growth, a defining feature of cancer.
