Polymorphism (variation at genetic level) arises due to mutation. Polymorphism in DNA sequence is the basis of genetic mapping of human genome as well as of DNA fingerprinting.
DNA fingerprinting involves identifying differences in some specific regions in DNA sequence, called as [2021]

DNA fingerprinting involves identifying differences in some specific regions in DNA sequence called as repetitive DNA, as in these sequences a small stretch of DNA is repeated many times.
Which of the following is not required for any of the techniques of DNA fingerprinting available at present? [2016]
Restriction enzymes
DNA-DNA hybridisation
Polymerase chain reaction
Zinc finger analysis
(4)
Any small, functional, freely folded domain in which coordination of one or more zinc ions is required to stabilise its structure is known as zinc finger. The zinc finger domains are widely dispersed in eukaryotic genomes and are actively involved in sequence specific binding to DNA/RNA and contribute in protein-protein recognitions.
