What is DNA polymorphism? Why is it important to study it?
DNA polymorphism is defined as the variation in DNA sequences arising through mutation at non- coding sequences.
A special type of polymorphism known as VNTR (variable number of tandem repeats) which 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 human genome. And, it forms the basis of DNA fingerprinting technique. The single nucleotide polymorphism is being used in finding the diseases and tracing of human history as well as in case of paternity testing.
