GEN-4500 Midterm: exam 3 studyguide
Document Summary
Transgenic animals - animals that have been genetically modified, through the introduction of foreign dna or rna, so that they overproduce, underproduce, lack the production of, or have modified expression of a particular protein. Most practical approach to understand gene function. Offspring will have the changes too unlike non-transgenic approaches. Factor ix kids - produce factor ix protein in mammary glands to be harvested for use in people suffering from deficiency (clotting protein, hemophilia b) Super salmon - gene enables it to grow year-round instead of only during spring and summer. On market in half the time than without gene (1. 5 years) Green mice - used to detect expression of transgene implantation. Featherless chicken - warm climates, chicken cannot survive with feathers. Cell culture - characterized gene sequences may be introduced into cell cultures and the protein product of the transferred gene, if secreted, may be collected from the culture medium.
