Detailed explanation-1: -These VNTRs vary from chromosome to chromosome in an individual. Its size varies from 0.1 to 20kb.
Detailed explanation-2: -VNTRs are found on many chromosomes and vary in length among different individuals. Each variant helps in personal or parental identification. VNTRs are an important source of genetic marker RFLP which is used in the linkage analysis of genomes. A banding pattern unique to each individual is produced by the VNTRs.
Detailed explanation-3: -Applications of VNTRs The technique may use PCR, size determined by gel electrophoresis, and Southern blotting to produce a pattern of bands unique to each individual. Therefore, VNTRs are being used to study genetic diversity (DNA fingerprinting) and breeding patterns in animals.
Detailed explanation-4: -The repeat unit of minisatellite DNA (also named VNTR previously) usually ranges from 10 to 100 bp and the block often extends between 100 bp and 20 kb.
