Satellite DNA is important because it
1. codes for protiens needed in cell cycle
2. shows high degree of polymorphism in population and also the same degree of
polymorphism in an individual, which is heritable from parents to children
3. does not code for protiens and is same in all members of the population
4. codes for enzymes needed for DNA replication.
