WebThe sequence-specific DNA cleavage activity of restriction endonucleases (REases), combined with other enzymatic activities that amplify and ligate nucleic acids, have enabled modern molecular … WebIn general, restriction enzymes cleave double-stranded DNA. Each restriction enzyme recognizes specific DNA sequences, and cleavage can occur within the recognition sequence or some distance away, depending on the enzyme. The recognition sequences are generally 4 to 8 base pairs (bp) in length, and cleavage can produce sticky ends (5′ …
WebAnswer (1 of 3): In bacteria the restriction enzymes (RE) play a protective role by destroying the foreign DNA, like that from the viruses. The viral DNA is non-methylated so that RE can differentiate between self DNA (which is methylated), from the foreign (which is non-methylated). This is a ki...
