Salvage Gene Is At The Root Of Many Mutations
...Rochester researchers show that REV1 leapfrogs the gap by inserting a defaultbase, cytosine, at the abasic site, allowing the unique zeta DNA polymerase -- recently announced by the same group ofscientists in Science -- to resume copying the DNA strand. This saves the cell from certain death, but its sur...Study Shows Songbirds Switch From Bugs To Berries To Fuel Fall Migration
