DNA fragments are labelled with a radioactive or fluorescent tag on the primer (1), in the new DNA strand with a labeled dNTP, or with a labeled ddNTP.

Gel electrophoresis apparatus – an agarose gel is placed in this buffer-filled box and an electric current is applied via the power supply to the rear. The negative terminal is at the far end (black wire), so DNA migrates toward the positively charged anode (red wire). This occurs because phosphate groups found in the DNA fragments possess a negative charge which is repelled by the negatively charged cathode and are attracted to the positively charged anode.
