Reverse two-hybrid analysis replication termination of prokaryotic and of some eukaryotic chromosomes occurs at specific sequences called replication termini (1, 2. Eukaryotic organisms usually have to synthesize much more genomic dna than is found in bacteria, and the template for replication is chromatin, not just dna also, and perhaps related to the effects of this protein-dna template, replication fork movement is considerably slower in eukaryotes, being only about 1,000 to 3,000 bp per min. Using prelabelling and backwards analysis it was shown that the time for dna replication (the c period) and the time between replication termination and cell division (the d period) were relatively invariant 1 over a wide range of growth rates, with numerous measurements, it was shown that escherichia coli strain b/r has a c period of 40 min.
