Localized sex in bacteria.

Author information

  • 1School of Biological Sciences, University of Sussex, Brighton, UK.


Electrophoretic studies suggest that bacterial populations consist of a number of independent clones and that genetic recombination is rare in nature. But DNA sequencing reveals that individual bacterial genes have a mosaic structure that could have arisen only by recombination. How can these observations be reconciled and what is their relevance to prokaryotic evolution?
