Summary. Les enzymes de restriction ou endonucléases reconnaissent et coupent l'ADN en une séquence spécifique. Ces enzymes sont produits naturellement chez les bactéries comme défense contre les bactériophages – virus qui infectent les bactéries. 2 Suivant le nombre de nucléotides reconnus, l enzyme de restriction coupe l ADN plus ou moins fréquemment. Par exemple, pour cette expérience nous utilisons deux enzymes différentes qui reconnaissent respectivement quatre et six nucléotides: (CCGG) et (GGATCC).

    These restriction enzymes are able to scan along a length of DNA looking for a particular sequence of bases that they recognize. This recognition site or sequence is generally from 4 to 6 base pairs in length. Once it is located, the enzyme will attach to the DNA molecule and cut each strand of the double helix. The restriction enzyme will continue to do this along the full length of the DNA type i restriction enzymes Introduction In the early 1960s, Werner Arber and Daisy Dussoix ( 1 , 2 ) provided evidence that degradation and methylation of DNA lay behind a phenomenon called ‘host-controlled variation in bacterial viruses’, reported a decade earlier ( 3–5 ) and reviewed by Luria ( 6 ).
