Dear student,                                                                                                                                    
Please find below the solution to the asked query          

The correct option is (a).

  • Southern blotting is a method used to detect specific DNA molecules from a mixture of DNA molecules.
  • Gel electrophoresis is the method of running DNA fragments on the gel. 
  • Cleavage refers to the cutting of DNA o get the DNA  fragments. 
  • DNA probing is the transfer of electrophoresed DNA fragments from gel to some other medium.
