Biotechnology and its Applications
12 lessons98 min5 simulations10 practice questions
This chapter takes the tools of recombinant DNA technology out of the lab and into farms, hospitals and law courts. It covers tissue culture and somatic hybrids, GM crops such as Bt cotton and RNAi-protected tobacco, recombinant insulin, gene therapy for ADA deficiency, molecular diagnosis, transgenic animals, and the ethics of GM organisms and biopiracy.
