There is a paternity dispute for a child'. Which techique can solve the problem? Discuss the priciple involved.

Explanation

DNA fingerprinting is the technique is used in solving the paternity dispute for a child . DNA fingerprinting is a techique of determining nuclotide sequences of cartain areas of DNA which are unique to each individual .
The basis of DNA fingerprinting is DNA polymorphism. Although the DNA from different indiviuals is more alike than differnet, there many regions of the humen chromosomes that exhibit a great deal of diversity . Such variable sequences are termed 'polymorphic' (meaning many forms).
A special type of polymorphism, called VNTR (Variable Number of Tandem Repeats), is composed of repeated copies of a DNA sequence that lie adjacent to one another on the chromosome . Since , polymorphism is the basis of genatic mapping of humen.
