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
Recombinant DNA Technology An example of a restriction fragment length polymorphism is different length fragments of DNA resulting from loss or gain of a restriction site an Eco RI cuts DNA at a different sequence than Hind III All of these cystic fibrosis results from a three base deletion in most cases but in other cases, other mutations are involved different length fragments of DNA resulting from loss or gain of a restriction site an Eco RI cuts DNA at a different sequence than Hind III All of these cystic fibrosis results from a three base deletion in most cases but in other cases, other mutations are involved ANSWER DOWNLOAD EXAMIANS APP
