The steps included in a cycle of Polymerase Chain Reaction are:
| 1. | initiation, elongation, and termination |
| 2. | transfection, transformation, and transduction |
| 3. | denaturation, annealing, and extension |
| 4. | restriction, electrophoresis, and elution |
Consider the two statements:
| I: | It is desirable to use restriction enzymes produce 'sticky ends' for cloning experiments in genetic engineering. |
| II: | If the donor DNA and the vector DNA are cut by such same restriction endonuclease, ligation of the two is easy. |
| 1. | Both I and II are correct and II explains I |
| 2. | Both I and II are correct but II does not explain I |
| 3. | Only I is correct |
| 4. | Both I and II are incorrect |

| 4. | It is a single stranded polynucleotide |
What limitation of traditional hybridization procedures used in plant and animal breeding can be overcome by recombinant DNA procedures?
| I: | Inclusion and multiplication of undesirable genes |
