Document Summary

Lecture 1 in vivo - use of nonhuman animals in experiments earliest reference to animal testing is greek - aristotle model species - organism studied by many researchers. Squid - giant axon c elegans - each cell is known. Ber ibery - rice - loss nerve muscle function - t h ia m i n def ic iency (b vitamin) Scurvy - deterioration of connective tissue - v itam i n c def ic iency www. notesolution. com. R ickets - vitamin d deficiency - bad calcium/phosphate absorption - bendy knees assimilation - process of nutrient acquisition and absorption. Energy content - must match metabolic demands of animal - in joules/ calories. Calor ic equ ivalent - energy content of a gram of some macromolecule. Sda ( specific dynamic action ) - = heat i ncre ment - energy used to. Digest food - important source of thermal energy net energy - used for other activities.

4. One of the great science fiction movies so far this century was Alfonso CuarÃ³nâs Children of Men (2006), in which infertility threatens humanity with extinction.

(a) P-element hybrid dysgenesis in the fruit fly Drosophila is a frightening illustration of a mechanism by which this might happen in an animal species. Do some background research on this phenomenon in order to explain its molecular basis.

(b) Xenotransplantation has been suggested as a temporary solution of the problem of getting sufficient replacement organs to meet current needs. Pigs have been suggested as a potential source of organs, but most research was halted due to worries about potential risks to not just organ recipients, but to the human species as a whole from porcine endogenous retroviruses. What are endogenous retroviruses, and why do these pose a potential risk to humans.

(c) The CRISPR-Cas system for gene editing has been used to remove all known copies of porcine endogenous retroviruses from a pig cell genome. Does this suggest that xenotransplantation should now proceed (a moratorium on research was in effect until recently)? Explain your reasoning.
