Abstract
DNA is presumably the primary site at which radiation damage has biological consequences1. Although lesions in single strands can be repaired after ultra-violet exposure2,3, it has not been shown conclusively that X-ray damage to bacterial DNA can be repaired. In order to study the latter problem, we have devised a method for assaying long pieces of single stranded DNA in order to facilitate the detection of a small number of breaks in single strands induced by X-rays.
