DNA fragments generated by the restriction endonucleases in a chemical reaction can be separated by:
1. Polymerase chain reaction
2. Electrophoresis
3. Restriction mapping
4. Centrifugation
| 1. | cutting of DNA into fragments |

| 3. | construction of recombinant DNA by joining with cloning vectors |
| 4. | isolation of DNA molecule |
1. DNA ligase
2. endonucleases
3. DNA polymerase
4. exonucleases
