Either positively or negatively charged depending on their size

Satellite DNA is important because it:

Shows high degree of polymorphism in population and also the same degree of polymorphism in an individual, which is heritable from parents to children.

Does not cade for proteins and is same in all members of the population.

Codes for enzymes needed for DNA replication.

Codes for proteins needed in cell cycle.
