Which of the following is not required for any of the techniques of DNA fingerprinting available at present?
Polymerase chain reaction
Zinc finger analysis
Restriction enzymes
DNA-DNA hybridization
As we discussed
Steps of DNA fingerprinting -
(a) Extraction of DNA from the sample cells.
(b) Amplification of DNA by PCR
(c) Restriction digestion of PCR Products
(d) Separation on Agarose gel electrophoresis
(e) Southern blotting
(f) Hybridization using labelled VNTR probe
(g) Detection by autoradiography
- wherein
This technique is widely used in forensic science for criminal cases
In DNA fingerprinting PCR Restriction enzymes and hybridisation techniques are used.
