PHLB09H3 Lecture Notes - Lecture 16: Cochlear Implant, Consequentialism, Somatic Cell
Document Summary
Dna: deoxyribonucleic acid: contains the chemical coding that directs the construction, development, and operation of cells, ensures the inheritance of traits from one generation to the next. Newborn screening is to say, in chunks. Genomes are the complete set of dna for a particular species. combined with environmental considerations: genetic testing is a lot of speculation and guesswork. These chunks are what we call genes: genes are what allow cells to specialize. Genetic disease is complicated: not usually down to one gene, but several, The base pairs aren(cid:495)t read individually (cid:523)like letters(cid:524) but more like words, that: can not determine what you(cid:495)ll be like with the genes that you have. Predictive testing: this may be a preventative measure. Diagnostic testing: may be mandatory in some hospitals. Carrier testing disease: confirm a genetic disease of somebody who has symptoms. Prenatal testing: testing fetus for genetic abnormality, 2nd trimester. Preimplantation genetic diagnosis (pgd: test they do on embryos before ivf.
