What Is Vntr Probe

VNTR is a region of the genome organized as tandem repeats while a probe is a short DNA or RNA sequence synthesized artificially in order to detect target sequences in a sample. So, this is the key difference between VNTR and probe.

How does VNTR different from probe?

VNTR is a small fragment of DNA containing tandemlyy repeated sequence, whose number and length vary among chromosome and individuals. VNTR shows a high level of polymorphism and is specific for different individual, whereas Probe is a small fragment of DNA or RNA used for identification of genes in biological system.

What is the role of VNTR in DNA fingerprinting?

(a) VNTR stands for Variable Number of Tandem Repeats. DNA fingerprinting involves identifying differences in some specific short nucleotide repeats called variable number tandem repeats (VNTR). This number of repeats is specific from person to person and are inherited.
