Cell survival depends on having a plentiful and balanced pool of the four chemical building blocks that make up DNA. However, if too many of these components pile up, or if their usual ratio is disrupted, that can be deadly for the cell. Chemists have discovered how a single enzyme maintains a cell's pool of DNA building blocks.
