Tools of recombinant DNA technology

Important tools of recombinant DNA technology are-

  • Restriction enzymes- Restriction enzymes are called as molecular scissors because these enzymes cut DNA at specific sites.
  • Cloning vector- Plasmids and bacteriophages have the ability to replicate within bacterial cells independent of the control of chromosomal DNA.
  • Competent host- The host should be competent enough to take up the foreign DNA.
  • Bioreactors- Bioreactor is the cylindrical vessel in which biological processes is carried out on a large scale.
