plasmid replication in bacteria
One problem is that at the end of linear fragments, the cell needs to be able to tell the difference between normal DNA ends and ends that are made when a double strand of DNA breaks. J. Gen. Microbiol. Beyond horizontal gene transfer: the role of plasmids in bacterial Every plasmid has its own origin of replication a stretch of DNA that ensures it gets replicated (copied) by the host bacterium. FOIA The size of naturally occurring plasmids ranges from roughly 1 kilobase to over 1 megabase, with the average plasmid DNA being less than 5% the size of the bacterial chromosome. 9, 522 (2018). & Eyre-Walker, A. B. S. A mathematical theory of natural and artificial selection, part V: selection and mutation. Math. If the plasmid is lost in a daughter cell, the antitoxin is rapidly degraded and the stable toxin kills the plasmid-free cell. Distance matrixes were corrected for multiple substitutions by the method of Kimura. 81, 011909 (2010). 11, 2452 (2020). Bottery, M. J., Wood, A. J. However, recent studies have revealed that the evolutionary impact of plasmids goes above and beyond their being mere gene delivery platforms. ori sequences are generally high in As and Ts.

Accessibility In recent years the understanding of initiation and regulation of plasmid replication in Escherichia coli has increased considerably, but it is only for the ColE1-type plasmids that significant biochemical data about the initial priming reaction of DNA synthesis exist. Plasmids are mainly found in bacteria, but they can also be found in archaea and multicellular organisms. Biochem. Accessibility https://doi.org/10.1089/mdr.2018.0407 (2019).

Introduction Plasmids since their discovery have been detected in many different genera. Howarth, S. Resistance to the bactericidal effect of ultraviolet radiation conferred on Enterobacteria by the colicine factor coli. Springer Nature remains neutral with regard to jurisdictional claims in published maps and institutional affiliations. We focus on new evidence that suggests that plasmids might accelerate bacterial evolution, mainly by promoting the evolution of plasmid-encoded genes, but also by enhancing the adaptation of their host chromosome. FEMS Microbiol. A plasmid is a small circular DNA molecule found in bacteria and some other microscopic organisms. Evol. Genet. Agents Chemother. Commun. The second problem with linear plasmids and chromosomes is that the lagging-strand template is hard to copy. In most cases, knowledge concerning plasmid replication is limited to regulation mechanisms. government site. Proc Natl Acad Sci U S A. The molecular mechanism of bacterial plasmid replication resembles the beginning of E. coli chromosome replication. In addition to the chromosome, bacteria often contain plasmids small circular DNA molecules. For further discussion, see the text. Rankin, D. J., Rocha, E. P. C. & Brown, S. P.
