Mutations in the p53 gene can lead to cancer by
A) causing the production of excessive amounts of relay proteins.
B) causing the production of a faulty protein that is no longer able to inhibit cell division.
C) promoting the expression of mRNA that can interact with DNA, resulting in new mutations.
D) increasing the production of growth hormones, which trigger faster cell cycles.

Question

Quizplus · Accepted Answer

The p53 gene codes for a protein that inhibits cell division or triggers apoptosis (programmed cell death) in case of DNA damage or other cellular stress. Mutations in this gene can result in the production of a faulty protein that is no longer able to perform these functions, leading to uncontrolled cell division and the formation of tumors. The other options listed are not directly related to the function of the p53 protein.
