Question

Satellite DNA is important because it :

• A. Codes for enzymes needed for DNA replication
• B. Codes for proteins needed in cell cycle
• C. Shows high degree of polymorphism in population and also the same degree of polymorphism in an individual, which is heritable from parents to children
• D. Does not code for proteins and is same in all members of the population

Answer 1

Answer: (C)

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

Answer 2

Satellite DNA forms the minor peak after centrifugation of DNA. These are repetitive DNA sequences that do not code for any protein. They show high degree of polymorphism and heritable from parents to children, this form the basis of DNA fingerprinting.
