Recombinant DNA Technology Some genetic diseases cannot be diagnosed by changes in restriction sites. Some of these can be detected by allele-specific oligonucleotide probes. These are PCR-amplified variable numbers of tandem repeats (VNTRs) short sequences that will hybridize only to a specific base sequence copies of the gene with an altered sequence so that a restriction site is inserted mutagenized copies of a gene PCR-amplified variable numbers of tandem repeats (VNTRs) short sequences that will hybridize only to a specific base sequence copies of the gene with an altered sequence so that a restriction site is inserted mutagenized copies of a gene ANSWER DOWNLOAD EXAMIANS APP
