Restriction endonucleases are enzymes which:
| 1. | make cuts at specific positions within the DNA molecule |
| 2. | recognize a specific nucleotide sequence for binding of DNA ligase |
| 3. | restrict the action of the enzyme DNA polymerase |
| 4. | remove nucleotides from the ends of the DNA molecule |
