WebWithin eukaryotic cells, mitochondria function somewhat like batteries, because they convert energy from one form to another: food nutrients to ATP. 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 ...
