Title: Why do bacteria produce restriction enzymes? Post by: pado on Oct 29, 2017 They are involved in defense against viruses.
They serve no function in bacteria and are just used as a molecular tool by scientists. They are involved in the identification of the bacterium's DNA. They are important in DNA replication. Title: Re: Why do bacteria produce restriction enzymes? Post by: bio_man on Oct 30, 2017 Restriction enzymes are part of the restriction-modification system; bacteria and Archea developed thus system as a defense against viruses. Bacterial methylases protect the host DNA by methylation in the sequences the restriction enzymes recognize, and the restriction enzymes fail to cleave methylated DNA.
