Detailed Solution
Satellite DNA consists of short sequences repeated many times; it forms separate small peaks during density gradient centrifugation.
These sequences do not code for proteins but show a high degree of polymorphism: the number of repeats (VNTR) differs from person to person.
This polymorphism is the basis of DNA fingerprinting, developed by Alec Jeffreys.
DNA fingerprinting is used in forensic science to identify criminals from blood, hair, semen or skin, and to settle paternity disputes.
Hence satellite DNA is a useful tool in forensic science.
