If a cancer cell develops a mutation inhibiting an intrinsic apoptosis pathway while also increasing cyclin D expression, which consequence follows?

A)Arrest in G1 phase induced
B)Telomere shortening accelerates greatly
C)DNA repair mechanisms are activated
D)Uncontrolled cell division accelerates

💡 Explanation

The increased cyclin D promotes progression through the cell cycle's restriction point while disabled apoptosis prevents programmed cell death, even with DNA damage, because the mutated apoptosis pathway fails to initiate cell destruction. Therefore, uncontrolled cell division accelerates rather than being halted or repaired, as the typical checkpoint controls are bypassed.
