Energy Transfer in Nucleoproteins

Summary

Artificial nucleoproteins have been made by complexing DNA with the proteins BSA, trypsin and salmine and also with the polypeptide, poly-L-lysine. These nucleoproteins have been irradiated with gamma-rays and examined using electron spin resonance techniques. In all four cases evidence has been found that the primary irradiation damage has occurred on the DNA moiety of the macromolecules, although this could not be unambiguously shown in the case of the trypsin-DNA complex.
