Question

Minisatellites or VNTRs are used in

• A. DNA fingerprinting
• B. Polymerase chain reaction (PCR)
• C. gene therapy
• D. gene mapping

Answer 1

The correct option is A DNA fingerprinting

The VNTRs or variable number tandem repeat is a location in a genome where a short nucleotide sequence is organized as a tandem repeat. These are used in DNA fingerprinting.
Minisatellite is a tract of repetitive DNA in which certain DNA motifs are typically repeated. Each individual has a unique pattern of minisatellites (except identical twins).
So, these minisatellites and VNTRs are used for DNA fingerprinting.

Thus, the correct answer is option (A).
