Q. The technique of $DNA$ fingerprinting relies on

AMUAMU 2014Molecular Basis of Inheritance

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.
