Spooling is:

a

Cutting of separated DNA bands from the agarose gel

b

Transfer of separated DNA fragments to synthetic membranes

c

Collection of isolated DNA

d

Amplification of DNA

✓ Correct answer: c)

Collection of isolated DNA

Explanation

During DNA extraction, the ethanol can be gently pushed down into the DNA solution by using a glass rod or wooden spooling stick. The charged DNA molecules move away from the ethanol and can be scooped up and swirled around a glass rod or wooden spooling stick. This is call DNA spooling. DNA spooling can isolate long strands of DNA from a solution.
