‘Walking molecules’ haul away damaged DNA to the cell’s emergency room. Amid the rise of CRISPR and genome editing, scientists are still learning more about DNA repair and its significance in aging and diseases such as cancer. The cell has its own paramedic team and emergency room to aid and repair damaged DNA, a new USC Dornsife study reveals.
The findings are timely, as scientists are delving into the potential of genome editing with the DNA-cutting enzyme, CRISPR-Cas9, to treat diseases or to advance scientific knowledge ab...
