Hints
The source of complementary RNA for RNAi in a eukaryotic cell could be:
| I: | An infection by viruses having RNA genomes |
| II: | Mobile genetic elements that replicate via an RNA intermediate |
| III: | Integration of phage DNA into the main chromosomal DNA of a eukaryotic cell |
| 1. | Only I and II | 2. | Only I and III |
| 3. | Only II and III | 4. | I, II and III |
