Recently, the power of cloning to rescue endangered or extinct species was demonstrated by applying nuclear transfer methods to save the mouflon, a species of wild sheep (left half of figure). This result piqued a fair amount of general interest, because of its possible implications for the return of other, more exotic, species from the jaws of extinction (as pictured on the right). Suppose a wealthy investor came to you with a proposal to create a real-life Jurassic Park (naturally, with far more detailed strategy to contain the animals), asking for your scientific analysis of their plan to use SCNT to bring back dinosaurs.

a. Considering all of the materials and technical steps involved in the process of nuclear transfer, list three problems you envision will be encountered by their team of scientists.

b. Speculate on how a researcher might overcome each of the obstacles you identified in (a), or state why you feel they may be insurmountable.

c. Given your analysis in (a) and (b), briefly comment on whether you think that the wealthy investor’s plan is feasible.
