← Human Body & HealthIf a growth factor receptor mutation constitutively activates cell division signaling in intestinal crypt stem cells, which consequence is most likely?
A)Enhanced DNA repair mechanisms activate
B)Uncontrolled proliferation overwhelms apoptosis✓
C)Increased differentiation reverses phenotype
D)Metabolic quiescence arrests cell growth
💡 Explanation
When growth factor receptors are constitutively active, it leads to continuous cell division signaling, overwhelming normal apoptotic pathways; because the checkpoints are bypassed, uncontrolled proliferation occurs. Therefore, the balance tips toward cell survival rather than programmed cell death, rather than quiescence or differentiation.
