- B PCR
- C Autoclaving
- D Centrifugation
Correct answer: A. Gel electrophoresis
Explanation: DNA fragments produced by restriction digestion are separated and visualised by agarose gel electrophoresis.
Recombinant DNA technology: a gene of interest and plasmid are cut by the same restriction enzyme, ligated into a recombinant plasmid, and introduced into a host cell.
