Answer #1

Answer to the first question is fourth option. All of the statements describe the pulse-field gel electrophoresis. It is used for surveillance and investigation of foodborne illness, it is result of frequency mapping and it is used only when the large DNA molecule stop the pulsing electric currents. Pulse field electrophoresis is used to separate large DNA molecules and it differs from normal electrophoresis as the direction of the current flowing through the gel matrix changes periodically between 3 directions with each electrode located 60 degrees apart.
