Answer:
D. All of the above
Explanation:
P53 is a tumor protein. It is often referred to as the "guardian of the genome". It can stop the cell from growing, repairs DNA and controls cell death, which is called apoptosis. As the cell is cycle goes on, p53 stops the growth of the cell when there is an error or damage in the DNA. This action prevents the defective cell from replicating. The p53 then signals the production of proteins that repair DNA. If the DNA is not fixable, it programs apoptisis.
If by some chance that the p53 gene are mutated, then it cannot do those functions, which may result in cancer or the uncontrolled replication of defective cells.

Carbohydrates are the sugar, starches, and fibers found in vegetables, grains, fruits, and milk products. They are the most important source of energy for your body.
They can’t change from bone to stomach cells. Once the cell has a dna set it will become what that dna is set for it to become and can’t change.
C, it is the powerhouse of a cell
