Q. 42 - Biology

Question

List the regulatory mechanisms that might be lost in a

cell producing faulty p53.

Step-by-Step Solution

Answer

(a.) Damaged DNA monitoring.

(b.) Apoptosis triggering

(c.) Recruitment of repair enzymes

Step 1. Introduction

p53 is a gene that controls the cell division and cell death.

Step 2. Explanation

Mutation in p53 gene causes loss of monitoring of quality of DNA, trigger apoptosis and recruitment of repair enzymes. 

These changes in a cell due to faulty p53 causes cancer due to continuous cell division.
