Question

In DNA fingerprinting, analysis is made of ________.

• A. Satellite DNA
• B. Moderately repetitive sequences
• C. Microsatellites
• D. Variable number of tandem repeats

Answer 1

The correct option is D Variable number of tandem repeats

• In DNA fingerprinting, analysis is made of a variable number of tandem repeats (VNTR). A variable number tandem repeat (VNTR) forms bands that are unique in every individual. It is used in the DNA fingerprint process that is useful in identifying criminals and even used to identify genetic relation between two individuals.
• Satellite DNA are highly repetitive DNA.
• Microsatellites are short tandem repeats that consist of 1 to 9 base pairs monomer repeating sequences.

Hence, the correct option is D.
