title: Temporal replication of an interspersed repeated sequence of mouse DNA.
abstract: The temporal replication profile of an interspersed repeated DNA sequence (variously named MIF-1, Bam and L1Md) of mouse was determined by isotope analysis of a resolvable restriction fragment differentially labeled in pre- and post-synchrony cultures. While the temporal replication profile of the fragment was similar to that of total nuclear DNA, an average time lag of about 20 min was evident for this interspersed repeated family (called Bam in this paper). In addition, the sequence organisation of Bam homologues were examined for the separable early- and late-replication domains of the hamster genome. The data suggest that late-replicating domains of the rodent genome are slightly enriched in Bam homologous sequences. Furthermore, this repeated sequence family has different sequence organisations in the separable replication domains of hamster.
