    The technique of DNA fingerprinting relies on

    A)  repetitive DNA                

    B)  mini-satellite DNA

    C)  Both (a) and (b)              

    D)  None of these

    Correct Answer: B

    Solution :

                     DNA fingerprinting is based upon the fact that the DNA constitution of an individual carries some specific sequences of nucleotides which do not carry any information for protein synthesis, These specific sequences are repeated many times and found at many places within the genome. These loci are known as the Variable Number Tandem Repeats (VNTRs) or mini-satellites. VNTR belongs to a class of satellite DNA called as mini-satellite.
