Nonrandom minichromosome replication in Escherichia coli K-12.

RESUMO

The intervals between rounds of chromosome and minichromosome replication were measured by density shift experiments and found to be similar. Thus the minichromosome, a lambda asnA oriC bacteriophage, mostly replicates once each division cycle rather than randomly, despite its high copy number. Slight differences between the chromosome and the oriC plasmid are explained.
