Plasmid Molecular Biology

  • Edward A. Birge
Part of the Springer Series in Microbiology book series (SSMIC)


Plasmids face many of the same problems as bacterial chromosomes. They must replicate themselves, synthesize appropriate gene products, and segregate at least one copy of the plasmid into each daughter cell at cell division. However, plasmids also maintain incompatibility functions that prevent other, similar plasmids from taking up residence in the same cell and in many cases can transfer their DNA to other cells. They exist in a characteristic low or high copy number relative to the bacterial chromosome. This chapter considers the various methods by which plasmids accomplish these tasks.
