    The bulk of DNA (other than repetitive) forms major peaks during density gradient centrifugation. The other small peaks are referred to as

    A) satellite DNA

    B) non-satellite DNA

    C) exonic DNA

    D) intronic DNA

    Correct Answer: A

    Solution :

    [a] Basis of DNA fingerprinting involves identifying the differences in some specific regions in DNA called repetitive DNA. These repetitive DNA are separated from the bulk genomic DNA as different peaks during density gradient centrifugation. The bulk DNA forms the major peak and other small peaks are referred to as satellite DNA.
