title: Restriction enzymes in cells, not eppendorfs.
abstract: Restriction enzymes are essential reagents to molecular biologists, but their relevance to bacterial populations is less obvious. Most bacteria encode restriction and modification systems and these are commonly considered to be a barrier to phage infection. Current evidence also supports a more general role for them in genetic recombination.
