Received March 8, 1978. Ultraviolet light induces more pyrimidine dimers and more repair replication in DNA that replicates within 2 to 3 hr of irradiation than in DNA that does not replicate during this period. This difference may be due to special conformational changes in DNA and chromatin that might be associated with semiconservative DNA replication.
