Question

DNA fingerprinting using Variable Number Tandem Repeats (VNTRs) is based on the observation that

• A. Each variant acts as an inherited allele, allowing them to be used for personal identification
• B. The DNA of VNTR loci is more stable than that of loci which code for proteins
• C. VNTR sequences show little variability
• D. VNTR loci are highly polymorphic

Answer 1

The correct option is A Each variant acts as an inherited allele, allowing them to be used for personal identification

A short DNA sequence repeated a variable number of times is referred to as Variable Number of Tandem Repeats or VNTR. Each variant acts as an individual allele which allows them to be used in DNA fingerprinting.

So, the correct answer is 'Option A'.
