Question

PCR and restriction fragment length polymorphism are methods for

• A. Genetic fingerprinting
• B. Genetic transformation
• C. DNA sequencing
• D. Study of enzymes

Answer 1

The correct option is A

Genetic fingerprinting

PCR can be used in DNA fingerprinting as a way to make numerous copies of isolated DNA. The process can selectively amplify a single copy of a desired sequence.

Restriction fragment length polymorphism is a method where variation in DNA between individuals is revealed by restriction enzymes. DNA is cut into fragments of different lengths in consequence of such variations. It is used forensically and in the diagnosis of hereditary disease.
