    Q:

    		 Which of the following is true regarding using dideoxynucleotides (ddNTPs) for DNA sequencing?
    		 

    A

    		 Restriction enzymes cut the target DNA into fragments, which are then separated and visualized with electrophoresis

    B

    		 The template strand is tagged with a radioactive isotope

    C

    		 ddATPs, ddCTPs, ddGTPs, and ddTTPs must be utilized in a separate environment from the dATPs, dCTPs, dGTPs, and dTTPs

    D

    		 A ddTTP can randomly and occasionally terminate the synthesis of DNA where an adenine occurs in the template strands
