Nature's photocopiers caught 'doodling'—scientists say it could revolutionize how DNA is written

New research has discovered that the molecular machines responsible for copying our DNA have a surprising hidden talent—an ability to create entirely new and highly sophisticated DNA sequences from scratch. The study, led by the University of Bristol, analyzes this curious "doodling" activity, showing for the first time that it can be steered and controlled. The findings not only help shed further light on how genetic information emerges, but could also present exciting new ways of writing long DNA sequences.
