# Programmable DNA insertion achieved without double-strand breaks

Researchers have developed a new method for precise DNA knock-in that avoids double-strand breaks, a major source of unwanted mutations in gene editing. The technique uses a programmable approach to insert genes efficiently and accurately. This advance could significantly improve the safety and efficacy of gene therapies for genetic disorders.
