the gene that cracked the cancer code

MEDICAL GENETICS. All of us have lurking in our DNA a most remarkable gene, which has a crucial job - it protects us from cancer. Known simply as p53, this gene constantly scans our cells to ensure that they grow and divide without mishap, as part of the routine maintenance of our bodies. If a cell makes a mistake in copying its DNA during the process of division, p53 stops it in its tracks, summoning a repair team before allowing the cell to carry on dividing. If the mistake is irreparable and the rogue cell threatens to grow out of control, p53 commands the cell to commit suicide. Cancer cannot develop unless p53 itself is damaged or prevented from functioning normally. Perhaps unsurprisingly, p53 is the most studied single gene in history. This book tells the story of medical science's mission to unravel the mysteries of this crucial gene, and to get to the heart of what happens in our cells when they turn cancerous
