At first Amgen tried using genetic engineering to create organisms that would extract oil from shale, man-made proteins that would make chickens grow faster and new specialty chemicals such as a cloned indigo, a substitute for the natural dye used to color blue jeans.

FORBES: Biotech Behemoth

Dr. LEE RYBECK LYND (Professor of Engineering, Adjunct Professor of Biology, Dartmouth College): In my lab, one of the big ideas we're working on, is to try to develop microorganisms using genetic engineering, that let us do, in one step, what we're now only able to do in more than one step.
