Question

Due to high degree of polymorphism ,size of VNTR varies from:--

• A. $0.1-2kb$
• B. $0.1-20kb$
• C. $0.01-20kb$
• D. $0.1-200kb$

Answer 1

The correct option is B $0.1-20kb$

Variable number of tandem repeats (VNTR) is a location in DNA where a short nucleotide sequence is organized as a tandem repeat with variations in length between individuals.

Variable number tandem repeats (VNTRs) are short nucleotide sequences (20–100 bp) that vary in copy number and the number of times the sequence repeats varies from about five to fifty times. So the VNTR's size varies between this range 0.1 to 2.0 kb.
