Question
Infertility and spontaneous abortion increase with age primarily due to higher production of oocytes with abnormal chromosome numbers. endometriosis. uterine fibroids. highly acidic or basic vaginal secretions. Blocked uterine tubes. places sperm into a woman's reproductive tract to fertilize an oocyte GIFT Sperm washing Gene Therapy IVF Intrauterine insemination Positional cloning cuts several copies of the human genome into pieces and aligns them to derive the overall sequence. determines the sequence of protein-encoding genes on a chromosome. seeks regions of the genome shared by the members of large families who have the same Mendelian disorder. identifies expressed sequence tags in genes of interest. scans and then sequence the human genome chromosome by chromosome, in size order. In the field of comparative genomics, what is compared? Genome structure among individuals in the same species Genomes from different species Single nucleotide polymorphisms in different ethnic groups Single nucleotide ploymorphisms associated with diseaseExplanation / Answer
1. With increasing age, the risk of abortion increases due to chromosomal abnormalities in aged eggs.
2. Intrauterine insemination is a technique in which sperm is introduced into the female vagina during the time of ovulation, to make artificial fertilization.
3. Positional cloning seeks regions of genome shared by the members of large families who have the same Mendelian disorder.
4. In comparatice genomics, genomes from different species is compared.
