The system, called a 'DNA typewriter', recorded cell relationships from the first cell division to 13.5 days after fertilization. This breakthrough could help explain birth defects, genetic disorders, and cancer.Why it mattersUnderstanding how a single cell becomes an entire organism is crucial for developmental biology. The DNA recording system allows researchers to study the emer
