New DNA repair enzyme makes mistakes to save lives of cells
.... For instance, normal wear and tear on a cell can cause
a base to break off the DNA strand, and enzymes, including POL-Q, repair the DNA by inserting bases where they are found missing. POL-Q also repairs bases that are damaged or chemically altered due to abuse or stress placed on the cell, such as from ...
