(i) Restriction endocleases for cutting the desrired DNA at desired places.
(ii) Gel electrophoresis for separating the desired DNA fragements.
Ligase enzyme for creating recombinant DNA molecule
(iii) Ligase enzyme for creating recombinant DNA molecule.
(iv) DNA delivery system like electroporation, microinjection, gene gun method, etc.
(v) Competant host (usually bacteria yeast) to take up the recombinant DNA.
