Answer: Electrophoresis
Explanation:
the procedure is usually used in life science laboratories to separate nucleic acids (DNA and RNA), which are negatively charged. An electric current at a certain voltage is passed through the electrophoresis tank containing the buffer. molecules to be separated are filled in the wells of a solidified gel ( usually agarose gel).As the current passes, the charged molecules move to opposite electrodes. The movement of molecules in in the gel also depends on the size of the molecules.
