Engineers set record for genetic changes in human cell

A Harvard team of genome engineers broke its previous record of genetic changes in a single human cell with a new total of 13,200. They targeted the repetitive LINE-1 DNA sequence found in 17% of the genome and used a modification of the CRISPR technique that replaces genetic letters rather than cutting open the double helix, which would have risked killing the cell.
