Text Solution

Verified by Experts

DNA polymorphism refers ro the variation in DNA arising through mutation at non-coding sequences.
A special type of polymorphism, called VNTR (Variable Number of Tendem 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 genetic mapping of humen genome, therefore, it forms the basis of DNA fingerprinting too.
