Recombinant DNA Technology When populations are small, gene frequencies can change from generation to generation and some alleles may become fixed in a population. This is called __________ . inbreeding genetic drift heterosis assortative mating inbreeding genetic drift heterosis assortative mating ANSWER DOWNLOAD EXAMIANS APP
Recombinant DNA Technology Knockout mice are created by creating a chimera by fusing cells from two different cell lines infecting the mouse with a retrovirus mutagenizing a mouse and selecting for mutant offspring transfecting embryonic stem cells with an altered gene sequence creating a chimera by fusing cells from two different cell lines infecting the mouse with a retrovirus mutagenizing a mouse and selecting for mutant offspring transfecting embryonic stem cells with an altered gene sequence ANSWER DOWNLOAD EXAMIANS APP
Recombinant DNA Technology An example of a restriction fragment length polymorphism is cystic fibrosis results from a three base deletion in most cases but in other cases, other mutations are involved an Eco RI cuts DNA at a different sequence than Hind III different length fragments of DNA resulting from loss or gain of a restriction site All of these cystic fibrosis results from a three base deletion in most cases but in other cases, other mutations are involved an Eco RI cuts DNA at a different sequence than Hind III different length fragments of DNA resulting from loss or gain of a restriction site All of these 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 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 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 ANSWER DOWNLOAD EXAMIANS APP
