Answer 1

15. The P53 protein is critical to the regulation of cell cycle because.........

correct option is..................(d). all of the above

• p53 is a tumour suppressor gene.
• The p53 gene halts cell division for repairing damaged DNA when there is a minor damage within the DNA replicated.
• P53 gene kills the cells (Apoptosis) when there is major damage within the DNA.
• The p53 gene produces a tumour suppression protein and controls unapproved division of cells.
• When the p53 gene gets mutated, it leads to abnormal cancerous growth.
