WebA mutation that knocks out the p53 gene can lead to excessive cell growth and cancer. The p53 gene is often called the "guardian angel of the genome". Damage to the cell's DNA leads to expression of the p53 gene. The p53 protein can: activate the p21 gene, which halts the cell cycle. turn on genes involved in DNA repair. activate "suicide genes ... WebAlexa Jacob. The Endoplasmic Reticulum in a eukaryotic cell is the transport network of the cell and it extends from and connects the nuclear membrane to the plasma membrane of a cell. But then whenever we draw a diagram of a typical plant or animal cell, we never extend it to the plasma membrane- we always leave it somewhere in the cytoplasm.
