How can one end be protected from the action of Exonuclease III, so that the molecule is not shortened from both the ends?

By making both the ends double stranded in nature

By using Phosphorothioate nucleotide analogue

By labelling one end with a radioactive compound

By increasing the time of exposure of the DNA molecule to the enzyme
