1. VNTR is the Variable Number of Tandem repeats. It is a chromosomal region. In which a small stretch of DNA sequence is repeated numerous times in a single location.
2. These VNTR produce a pattern of bands which is unique for each individual. These VNTR are used to identify criminals in forensic departments.
3. DNA fingerprinting is not an option for bacteriophage as it does not have repetitive sequencing portions like in VNTR’S so a pattern of bands would not be formed. Bacteriophagehas a small genome that has all the coding sequences.
