title: Repetitive plasmid sequences generate DNA fingerprinting patterns in mammals.
abstract: Bacterial plasmids with stringently regulated copy numbers have directly repeated DNA sequences, termed iterons, in the vicinity of their replication origins. These sequences bind a specific protein exerting a key role in the initiation of plasmid replication. Plasmids P1, pSC101 and RFS1010 have different iteron sequences and belong to three different incompatibility groups. Used as DNA probes each of these plasmids generates specific patterns in mammals similar to those obtained by the DNA fingerprinting technique. The iteron-containing regions were identified as the part of the plasmids responsible for those patterns by using polymerase chain reaction (PCR) amplified DNA segments that contained the iteron regions as probes.
