Sequence limits of DNA strands in the arrest replication fork at the Bacillus subtilis chromosome terminus.

Abstract

The DNA sequence limits of the leading and lagging strands in the arrested clockwise replication fork at the terminus of the Bacillus subtilis chromosome have been investigated. On the basis of hybridization to synthetic oligonucleotides corresponding to known positions in the terminus region sequence it has been shown that neither the leading nor lagging strands, as they approach terC, traverse the distal inverted repeat, IRI. But a small fraction of the leading strands pass through the proximal inverted repeat, IRII. This is consistent with IRI being the functional inverted repeat in arresting the clockwise fork. But most of the forks appear to stop at least 100 nucleotides short of IRI, and at various positions extending over a distance of at least 100 nucleotides.
