Recombinant DNA Technology Which of the following is correct in terms of determination of location of genetic traits? Known protein coding sequences are too far apart to allow linkage determination for most new genes None of these Restriction sites allow DNAs to be digested Protein-coding genes are always associated with a restriction pattern Known protein coding sequences are too far apart to allow linkage determination for most new genes None of these Restriction sites allow DNAs to be digested Protein-coding genes are always associated with a restriction pattern 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 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 PCR-amplified variable numbers of tandem repeats (VNTRs) ANSWER DOWNLOAD EXAMIANS APP
Recombinant DNA Technology When populations are small, gene frequencies can change from generation to generation and some alleles may become fixed in a population.
