In agarose gel electrophoresis, the DNA fragments produced by restriction enzyme digestion:
| 1. | will move towards anode with smaller fragments moving farther than the larger segments |
| 2. | will move towards anode with larger fragments moving farther than the smaller segments |
| 3. | will move towards cathode with smaller fragments moving farther than the larger segments |
| 4. | will move towards cathode with larger fragments moving farther than the smaller segments |
