What is one potential result of DNA mutations in terms of cellular behavior?

DNA mutations can significantly alter how cells behave, and one notable potential result is the promotion of uncontrolled growth. This occurs when mutations affect genes that regulate the cell cycle, which includes genes responsible for controlling cell division and apoptosis (programmed cell death).

When mutations activate oncogenes—genes that promote cell division or suppress tumor suppressor genes—cells may begin to proliferate uncontrollably. This uncontrolled growth is a hallmark of cancer and can lead to the development of tumors. Additionally, such mutations can interfere with the normal signals that typically keep cell growth in check, further contributing to aberrant cellular behavior.

In contrast, the other options do not align with the implications of DNA mutations in cellular behavior. While certain mutations can lead to increased cellular death, that outcome is not a direct or universal result of mutations. Similarly, mutations do not ensure normal growth processes; rather, they can disrupt these processes. Lastly, while some mutations may confer disease resistance, many mutations increase the risk of developing conditions, including various diseases. Thus, the potential for DNA mutations to lead to uncontrolled growth accurately reflects a significant concern in cellular biology and cancer research.
