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.
