Controversial Findings Help Explain Evolution of Life


CORVALLIS, Ore. - Chemists at Oregon State University have pioneered a
controversial theory about how supposedly-stable DNA bases can be pushed
into a "dark state" in which they are highly vulnerable to damage from
ultraviolet radiation - an idea that has challenged some of the most basic
concepts of modern biochemistry.

But what do they mean by 'damage from ultraviolet radiaiton'?
Do they mean only pyrimidine dimers? If so then it would not attack
all DNA just adjacent pyrimidines. If other UV damage, what kind?
Too many papers just leave it at the vague UV damage.
The specifics are important IMO.
