Human p53 is a tumor-suppressor gene located on chromosome 17. The function of this genel is to prevent cells with damaged DNA from undergoing mitosis. What would most likely result if there were a mutation that decreased the function of the p53 gene? Abnormal cells would continue to divide. Damaged cells would attack healthy cells. O Affected cells would produce more proteins. Germ cells would undergo only one meiotic division.

Mitochondria is the cell organelle that produced the energy that is needed in the body system in form of atp, that is why it is called the power house of the cell. energy is needed by the living organisms to carry out the activities which sustain life.  if the mitochondria is destroyed atp will not be produced. if the mitochondria is destroyed, energy production will stop and the affected living organism will not have the energy to carry out the necessary life processes; this will lead to the death of the organism.
