Write the full form of VNTR. How is VNTR different from “Probe‟?
VNTR stands for Variable Number Tandem Repeat.
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. These fragments are prepared for commercial and hybridization technology either for finding complementary sequence or in the diagnosis of some diseases.
