Spooling is:
Collection of isolated DNA
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.
