the conclusions are that 1 ) sces seem to be formed after dna synthesis ( by exchanging post-replicative dna portions ) , but , obviously , very near to the replication fork and 2 ) that under our experimental conditions about 0.065 sces per picogram of dna per cell cycle occur as a consequence of chromosome replication , this frequency being increased by brdu-substitution .
