Correct answer

C. The bulk DNA forms a minor peak and the other large peaks are referred to as satellite DNA.

Step-by-step solution

DNA fingerprinting involves identifying differences in some specific regions in a DNA sequence called repetitive DNA, because in these sequences, a small stretch of DNA is repeated many times. These repetitive DNA are separated from bulk genomic DNA as different peaks during density gradient centrifugation. The bulk DNA forms a major peak and the other small peaks are referred to as satellite DNA. Depending on base composition (A : T rich or G:C rich), length of segment, and number of repetitive units, the satellit
