How is apoptosis related to cancer development?
a. Cancer only occurs in cells capable of apoptosis.
b. Apoptosis increases the risk for DNA mutations.
c. The process of carcinogenesis suppresses or inhibits apoptosis.
d. Cancer cells with large amounts of apoptosis are more resistant to chemotherapy.
C
Normal cells have a finite life span. When a normal cell reaches the end of this life span the cell responds to signals for programmed cell death (apoptosis). The purpose of apoptosis is to ensure each organ has an adequate number of cells at their functional peak. Most cancer cells have an enzyme that prevents apoptosis, allowing these cells to have an unlimited life span (are "immor-tal").
