Question

Quizplus · Accepted Answer

Recombinant DNA technology has been used to produce medically useful proteins that are normally present in low amounts in animals and are difficult to purify. Expression vectors, such as plasmids, are commonly used to obtain these products in large amounts. The correct option is B as it correctly describes the process. Option A talks about hormones which is not the only product made by recombinant DNA technology. Option C talks about detecting hormones rather than producing them. Option D talks about detecting proteins rather than producing them. Option E mentions plasmid but does not describe the process accurately.
