Satellite DNA is important because it:
Codes for proteins needed in the cell cycle.
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.
Does not code for proteins and is the same in all members of the population.
Codes for enzymes needed for DNA replication.
satellite DNA sequences normally do not code for any proteins but show a high degree of polymorphism. This polymorphism is the basis of DNA fingerprinting. The text highlights that DNA from every tissue of an individual shows the same degree of polymorphism and these polymorphisms are inheritable from parents to children.
