What can be the purpose of a fill-in reaction in restriction digestion work?

Answer and explanation

Correct answer: Converting sticky ends into blunt ends

A fill-in reaction is used when a DNA fragment has a single-stranded overhang and the experimenter wants to convert it into a blunt end. A DNA polymerase adds complementary nucleotides to the recessed strand by using the existing strand as a template. When the overhang is filled, both strands end at the same position and the end becomes blunt.

Therefore option A is correct. This treatment can make the fragment suitable for a blunt-end cloning strategy, although blunt-end ligation may be less efficient than joining compatible sticky ends. The reaction does not change DNA into RNA, melt the gel, or store an enzyme. Its specific purpose is to modify the physical ends of DNA by synthesis of the missing complementary bases.
