VNTR (Variable Number Tandem Repeats) refers to a region of DNA where a short nucleotide sequence is repeated multiple times in a row. The number of repeats can vary significantly between individuals.
The size of the VNTR typically ranges from 0.1 to 20 kilobases (kb). These variations are useful in genetic analysis, such as DNA fingerprinting, for identifying genetic differences between individuals.
