Question

P53 often ushers in _______ in response to its activating signals

Answer 1

The p53 protein often ushers in cell cycle arrest and apoptosis in response to its activating signals.

Step-by-step explanation:

The p53 protein, a tumor suppressor gene, often ushers in cell cycle arrest and apoptosis in response to its activating signals. When p53 detects DNA damage or other cellular stressors, it activates genes required for DNA repair. If repair efforts fail, p53 can trigger cell death to prevent the propagation of damaged DNA in daughter cells.
