If a growth factor receptor mutation bypasses internal checkpoints within a cancer cell, which consequence is most likely, thus disrupting normal cellular processes?

A)Increased cellular differentiation signaling
B)Enhanced DNA repair enzyme production
C)Accelerated cellular nutrient uptake
D)Inhibition of programmed cell death

💡 Explanation

The loss of cell cycle checkpoints allows unchecked proliferation, which inhibits apoptosis because these checkpoints normally trigger cell death pathways when errors are detected; therefore, cancer cells continue to divide rather than undergo programmed death, which would limit tumor growth.
