Explain the significance of satellite DNA in DNA fingerprinting technique.

Satellite DNA consists of highly repetitive and generally non-coding DNA. It is very significant in DNA fingerprinting for the following reasons:

i. It shows high degree of polymorphism which forms the basis of DNA fingerprinting

ii. Different tissues in the body show the same degree of polymorphism and thus are useful as an identification tool in the forensic application.

iii. They are inheritable from parents to offsprings and  can be used for paternity testing.
