Functions of Taq DNA Polymerase in PCR Reaction

Variable Number Tandem Repeats or VNTR marker is a minisatellite DNA marker with various tandem repetitions of specific sequence present on a variety of chromosomes between individuals cluster and oriented together in same direction, VNTR marker initiate by extracting DNA and digest DNA with restriction enzymes to obtain multiple repeats sequence in form of bands on gel electrophoresis and hybridize by DNA probe to detect repeated sequence, VNTR marker classify as highly polymorphic and co-dominant marker with multiple loci by creating banding pattern that is unique for each individual, VNTR markers use in genetic linkage studies by finding difference allele frequencies and genetic diversity within group of organisms and DNA fingerprinting by studying specific genes position for genetic map which may be useful in gene expression studies (Watch Related Video in #geneticteacher) #geneticteacher
