Question
Compare polymerase chain reaction and gene cloning.
✓
Answer
| S.No. | Polymerase Chain Reaction = PCR | Gene Cloning |
| 1 | It requires very little DNA, even one copy of the gene is sufficient. | It requires more DNA. |
| 2 | This is an inexpensive method because it does not require expensive restriction enzymes, ligases and vector DNA. | All these are required in this, hence it is an expensive method. |
| 3 | It requires less time (4-5 hours), labor and efficiency. | It requires more time (2-4 days), labor and efficiency |
| 4 | It requires less time (4-5 hours), labor and efficiency. | It has limited applications. |
| 5 | This is a completely automatic method | It is not automatic. |
