Which of the following is a characteristic of the protein product of the p53 tumor suppressor gene? It slows down the rate of DNA replication by interfering with the binding of DNA polymerase to the DNA template. It allows cells to pass on mutations due to DNA damage. It speeds up the cell cycle. It is an activator for other genes.
