Ancient defense mechanism may still be protecting us
A complex DNA error-correction system that likely evolved from an ancient self-defense mechanism is still active in nearly every organism, turning primeval genetic invaders' tricks against them and into useful cell functions. The mechanism, discovered by researchers at the University of Rochester, ensures that any foreign genetic material that has been inserted into the cell's DNA is neutralized before being passed on to the next generation.
