1. Portray Trisomy 21st, Turner’s, Klinefelters’s, Patau’s, Edward’s, Jacob’s, and XXX syndromes (Pp. 49, 57, class notes) Trysomy 21st aka Down Syndrome. Genetic condition in the 21st pair of chromosomes in which the female has an extra X chromosome for a total of 47. Turner's occurs in the 23rd pair of chromosomess in which the male is missing the Y chromosome. The male will now have 45 chromosomes instead of 46 and may not have fully developed sex organs . Klinefelter's occurs in the

called genetic mutations. Genetic conditions such as Huntington Disease or Cystic Fibrosis are caused by mutations in single genes.’ According to in a Chinese group from Sun Yat-Sen University reported that they had taken “human triponuclear embryos” and successfully cut out the mutant DNA that causes the lethal human disease β-thalassemia, and eliminated the disease entirely from the embryo. Using this same method in ‘The Death Collectors’, the genetic mutation believed to cause

Unit II: Genetics Brief Overview Reading: Chapters 3, 4, 9-12, 14 (Note: you have reviewed much of this already) The earth is teeming with living things. We can easily see some of the larger organisms—trees, grass, flowers, weeds, cats, fish, squirrels, dogs, insects, spiders, snails, mushrooms, lichens. Other organisms are everywhere, in the air, in water, soil and on our skin, but are too small to see with the naked eye—bacteria, viruses, protists (single celled eukaryotes such as amoebae)

at 20%) and large brood size of C. elegans facilitate genetic manipulations (Brenner, 1974; Herman and Horvitz, 1980). We describe here the isolation and characterization of mutations that prevent the initiation of programmed cell death in C. elegans, causing cells that would normally die to survive instead. These mutations define two genes, ted-3 and ted-4, that may be involved in determining which cells express the fate of programmed cell death. Summary The wild-type functions of the genes ted-3

The neurofibromatoses (NF) are genetic disorders of the nervous system. At this time two distinct forms are known: NF1 and NF2. One baby in every four thousand is born in the United States with NF1. It is one of the most common genetic disorders, affecting some one hundred thousand americans. NF2 is less common and occurs in only one and every forty thousand births. In both forms of NF severity of symptoms vary greatly. The effects can be severely disabling, mildly disfiguring or can

Non-Small-Cell Lung Cancer Lung cancer, the most preventable cancer, it is the leading cause of cancer-related deaths in men and women in Canada. In 2008, it was estimated that there would be 23,900 new cases (12,600 men and 11,300 women) of lung cancer in Canada and that there would be 20,200 deaths (11,000 men and 9200 women) from lung cancer in Canada (Lewis, Heitkemper McLean, Dirksen Ruff, O’Brien Graber, & Bucher). Non-small-cell lung cancer (NSCLC) is a term for different types of lung

to his doctors office inquiring about genetic testing. Jackson recently married, and his wife Alisha is anxious to start a family. Unfortunately Jackson does not share Alisha's enthusiasm because he fears that he is a carrier of a deadly genetic mutation. Just five years ago Jackson's mother was diagnosed with Huntington's Disease at the age of 43 and Jackson's grandmother succumbed to the disease at the age of 68. Jackson is an only child and although unconfirmed and heavily denied by his family
