Chapter 16 Extrachromosomal Replication

Chapter 16 Extrachromosomal Replication. 16.1 Introduction. Bacterial extrachromosomal genomes fall into two general types: plasmids and bacteriophages (phages). Some plasmids, and all phages, have the ability to transfer from a donor bacterium to a recipient by an infective process.
