Quotes by Bern Kohler

“Even though paired bases are connected by weak chemical bonds, its the interactions that take place without chemical bonds – the interactions between stacked bases – that are much more important for dissipating UV energy.”

“It turns out that you cant extrapolate the results of base pairs to whole strands of DNA.”

“The ability to observe what happens to electronic energy in DNA on such short time scales also extends the hope that methods such as ours can finally determine how DNA is damaged by UV light in the first place.”

“This slow relaxation of energy is utterly different from the mechanism in single bases that transforms the energy into heat in less than a trillionth of a second.”

“In fact, so much attention has been paid to base pairing that this other interaction, base stacking, has been neglected.”
