What are satellite DNA in a genome ? explain their role in DNA fingerprinting
Asked by pksunilnair | 24th Mar, 2018, 05:17: PM
Satellite DNA are DNA sequences that contain highly repetitive DNA which means that a single sequence is repeated many times over.
The variation between individuals in the lengths of their DNA satellites forms the basis of DNA fingerprinting.
They are divided into minisatellites and microsatellites whose characteristic makes them simple for identification beteween two samples as the DNA is polymorphic. They are also inheritable from parents to offspring and can be used for paternity testing.
