| Abstract: | Heteroduplex analysis shows that a cryptic plasmid extracted from the male phage-sensitive strain, RP42, is a deletion mutant of F and lacks the segment with F-coordinates 8.5F to 17.6F. Consideration of the sequence deleted in F shows that the molecular recombination event between γδ and ?ζ DNA sequences actually occurs only between specific short segments at the ends. |
