Satellite DNA is important because it:
| 1. | Codes for proteins are needed in the cell cycle. |
| 2. | Shows a high degree of polymorphism in the population and also the same degree of polymorphism in an individual which is inheritable from parents to children. |
| 3. | Does not code for proteins and is the same in all members of the population. |
| 4. | Codes for enzymes needed for DNA replication. |

Gene regulation governing lactose operon of E. coli that involves the lac I gene products is:
| 1. | positive and inducible because it can be induced by lactose. |
| 2. | negative and inducible because repress or protein prevents transcription. |
| 3. | negative and repressible because repress or protein prevents transcription. |
| 4. | feedback inhibition because excess of β galactosidase can switch off transcription. |
