Options

  1. Acentrifugation
  2. Bpolymerase chain reaction
  3. Celectrophoresis
  4. Drestriction mapping

Correct answer

C. electrophoresis

Step-by-step solution

DNA fragments generated by the restriction endonucleases in a chemical reaction can be separated by electrophoresis. The polymerase chain reaction is simply DNA replication in a test tube. Restriction mapping is the process of obtaining structural information on a piece of DNA by the use of restriction enzymes, e.g., endonucleases that recognise specific 4 to 8 base regions of DNA.
