What is a key difference between a normal cell and a cancerous cell?
A
Normal cells divide uncontrollably, while cancerous cells have regulated division.
B
Normal cells can metastasize, while cancerous cells remain localized.
C
Normal cells undergo apoptosis when damaged, while cancerous cells do not.
D
Normal cells have mutated DNA, while cancerous cells have stable DNA.
Verified step by step guidance1
Understand the concept of apoptosis: Apoptosis is a programmed cell death process that occurs in normal cells when they are damaged or no longer needed. This is a crucial mechanism to prevent the proliferation of potentially harmful cells.
Recognize the behavior of cancerous cells: Cancerous cells often evade apoptosis, allowing them to survive and proliferate even when they are damaged or abnormal. This evasion of apoptosis is a hallmark of cancer.
Differentiate between normal and cancerous cell division: Normal cells have regulated cell division, meaning they divide in a controlled manner. In contrast, cancerous cells divide uncontrollably, leading to tumor growth.
Identify the role of DNA mutations: Normal cells typically have stable DNA, whereas cancerous cells often have mutations that contribute to their uncontrolled growth and ability to evade apoptosis.
Conclude the key difference: The key difference is that normal cells undergo apoptosis when damaged, while cancerous cells do not, allowing them to continue dividing and potentially leading to cancer progression.
