There are four classes of restriction endonucleases: types i, ii,iii and iv all types of enzymes recognise specific short dna sequences and carry out the.
A restriction enzyme or restriction endonuclease is an enzyme that cleaves dna into fragments the term restriction enzyme originated from the studies of phage λ, a virus that infects bacteria, and the phenomenon of host-controlled restriction and detailed articles about certain restriction enzymes: ecori, hindiii, bglii.
