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′ … WebRestriction enzymes cut DNA strands at specific sequences to form ‘sticky ends’. The plasmid and the isolated gene are joined together by DNA ligase enzyme. If two pieces of DNA have matching sticky ends (because they have been cut by the same restriction enzyme ), DNA ligase will link them to form a single, unbroken molecule of DNA. Test ...
