PHLB09H3 Lecture Notes - Lecture 10: Thought Experiment, Stem Cell, Embryonic Stem Cell
Document Summary
Identify, predict genetic disease: alter genes to devise cures. Dna: chemical directing production of proteins for biological function. Gene: dna sequence containing production code: determines most characteristics, faulty code causes disease and disability. Genetic testing: predictive testing whether you are a carrier, diagnostic testing whether you have a disease, carrier, prenatal testing an embryo, pre-implantation genetic diagnosis (pgd) Ivf embryo developed in glass prior to implantation genetic disease is tested: newborn screening. Problems: probability, environmental factors likelihood of gene expression could be altered by the environment, too many diseases we know lots about genetic diseases. The more we know = longer list of cures we need to find: desire to know whether or not people want to know whether they have a genetic disease, could change family dynamic, social stigmas, Responses to knowledge: personal, familial could change family dynamic, social, financial unfair treatment from an employer or not being supported by medical insurance. Tested for suspected, incurable disease: confront challenge.
