Recombinant DNA Technology Both DNA gel electrophoresis and SDS-PAGE of proteins are similar because All of these both techniques rely on a constant charge to mass ratio in both cases molecules migrate to the anode both techniques utilize the sieving properties of gels All of these both techniques rely on a constant charge to mass ratio in both cases molecules migrate to the anode both techniques utilize the sieving properties of gels ANSWER DOWNLOAD EXAMIANS APP
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 short sequences that will hybridize only to a specific base sequence PCR-amplified variable numbers of tandem repeats (VNTRs) copies of the gene with an altered sequence so that a restriction site is inserted mutagenized copies of a gene short sequences that will hybridize only to a specific base sequence PCR-amplified variable numbers of tandem repeats (VNTRs) copies of the gene with an altered sequence so that a restriction site is inserted mutagenized copies of a gene ANSWER DOWNLOAD EXAMIANS APP
