In gel electrophoresis, DNA fragments move toward the:

Question

Accepted Answer

B. Positive electrode (anode), because DNA is negatively charged

DNA has a negatively-charged phosphate backbone, so it moves toward the POSITIVE electrode (anode).
Smaller fragments migrate faster through the gel pores.
EtBr or SYBR Green stains DNA for UV visualisation.

Answer

Negative electrode (cathode), as DNA carries positive charge

Answer

Neither electrode, since DNA is neutral

Answer

Both electrodes equally, the field randomises movement
