Satellite DNA is important because it:

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

Correct answer: does not code for proteins and is same in all members of the population

Solution

Satellite DNA is a type of repetitive DNA that does not code for proteins and is present in all members of a population.
