Variable Number Tandem Repeat

A Variable Number Tandem Repeat (or VNTR) is a location in a genome where a short nucleotide sequence is organized as a tandem repeat. These can be found on many chromosomes, and often show variations in length between individuals. Each variant acts as an inherited allele, allowing them to be used for personal or parental identification. Their analysis is useful in genetics and biology research, forensics, and DNA fingerprinting.

Famous quotes containing the words variable, number, tandem and/or repeat:

    There is not so variable a thing in nature as a lady’s head-dress.
    Joseph Addison (1672–1719)

    The basis of successful relief in national distress is to mobilize and organize the infinite number of agencies of self help in the community. That has been the American way.

    The Cad is the entire epitome, the complete blossom and fruit in one, of what we are told is an age of culture. Behold him in the vélodrome as he yells insanely after his kind as they tear along on their tandem machines in a match, and then ask yourself candidly, O my reader, if any age before this in all the centuries of earth ever produced any creature so utterly low and loathsome, so physically, mentally, individually, and collectively hideous?
    Ouida [Marie Louise De La Ramée] (1839–1908)

    It is the soothing thing about history that it does repeat itself.
