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

The correct option is 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

• Satellite DNA is the region which is comprised of repeated sequences. This region does not encode for any protein or enzymes.
• The region shows a high degree of polymorphism in the population or between two different organisms.
• This property can be used for DNA fingerprinting analysis. The satellite DNA shows the same degree of polymorphism in related individuals.
• This property can be used for paternity testing in which the offspring and parent have the same degree of polymorphism.

Thus, the correct answer is option C.
