Question

Satellite DNA is important because it
A. codes for proteins needed in cell cycle
B. show high degree of polymorphism in population and also the same degree of poylmorphism in an individual , which is heritable from parents to children
C. does not code for proteins and is same in all members of the population
D. codes for enzymes needed for DNA replication

Answer 1

Correct Answer - B
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 , thus form the basis of DNA figerprinting.
