Satellite DNA is important because it:

Satellite DNA is important because it:

Options

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

Correct answer

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

Step-by-step solution

Satellite DNA are the repetitive DNA which do not code for any protein. They show high degree of polymorphism and forms the basis of DNA fingerprinting.

Since DNA from every tissue from an individual show the same degree of polymorphism, they become very useful identification tool in forensic applications.
