Figure 28-5: Model of N15 plasmid prophage replication (pathway A) and two other principal strategies to replicate linear DNAs with covalently closed ends (pathways B and C). A1 - protelomerase cuts before completion of replication, resulting in an Y-like structure. A2 - replication is finished before protelomerase cutting, circular head-to-head dimer. telL, telR, left and right telomere ends of N15 prophage; telN, protelomerase gene; ori, replication initiation site. Dotted lines indicate newly synthesized strands. Arrowheads indicate positions of cuts.
