id: GO:0009307
name: DNA restriction-modification system
namespace: biological_process
type: go
obsolete: False

Description: A defense process found in many bacteria and archaea that protects the organism from invading foreign DNA by cleaving it with a restriction endonuclease. The organism's own DNA is protected by methylation of a specific nucleotide, which occurs immediately following replication, in the same target site as the restriction enzyme.
