As we learnt ,
DNA fingerprinting -
It involves identifying differences in some specific region in DNA sequence called as repetitive DNA, because in these sequences, a small stretch of DNA is repeated many times.
- wherein
These repetitive DNAs are seperated from bulk genomic DNA as different peaks during density gradient centrifugation.
