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. |
