Question

Are VNTRs human specific?

Answer 1

A location in genome which consist of short nucleotide sequence is arrangef as a tandem repeat .They can be found on many chromosomes and generally show variation bin length , among individuals .Each and every variant act as a inherited alleles and hence make them useful for personal or parental identification.

VNTR's have its application in forensic criminal investigation , through DNA fingerprinting and CODIS database. After the extraction NB and isolation of DNA their size is determined by gel electrophoresis which produce a pattern of bands which are unique to each individual.while testing it with the group of independent VNTR marker the chances of unrelated individual having same allelic pattern is extremely low.
