Illustration of a molecular model of a tumour suppressor p53 (brown, cyan and ochre) bound to a spiral strand of DNA (deoxyribonucleic acid, orange and blue) genetic material. Tumour suppressor p53 is a protein that binds to a specific DNA gene sequence that regulates the cell cycle and p53 blocks this sequence and is thus involved in preventing cancer.
