The p53 gene is responsible for helping build a protein inside of cells that plays a critical role in repairing damaged DNA or

deciding whether or not to initiate apoptosis If this gene is damaged and the protein is faulty, severe consequences may result
Predict what may happen to a cell that has a damaged p53 gene.
A) The cell may become cancerous.
B) The cell may experience uninhibited and out of control cell division
C) The cell may accumulate multiple mutations.
D) The cell will most likely self-destruct.
(All that apply)

Answer:

A cell that has Damaged p53 gene , A) may become Cancerous; B) may experience uninhibited and out of control cell division; C) may accumulate multiple mutation.

Step-by-step explanation:

  • p53 gene is a tumor suppressor gene that encodes a polypeptide that acts as a transcription factor.
  • Mutation in p53 is associated with 50% of human cancers.
  • Loss of p53 removes DNA damage check point.
  • Mutation in p53 prevents DNA repair and the apoptosis of cells that contain irreparable damage.
  • as a result the cells may accumulate multiple mutations.
  • Since Functional p53 promotes DNA repair and arrest the cell cycle if a damaged DNA is present; any mutation in p53 may result in uncontrolled cell growth and tumor formation.
