Humans and a bacterium make human insulin.How is this possible?
A)The human insulin gene appears naturally in the bacteriA.
B)The human insulin gene is a mutated form of a bacterial gene for bacterial insulin.
C)The human insulin gene was inserted into a bacterium's genome,and since the genetic code is nearly universal,the bacterium is able to produce human insulin.
D)The human insulin gene appears in bacteria that have been exposed to radiation treatments for diabetes.
E)The human insulin gene appears naturally in the bacteria that is an inhabitant of the GI tract of diabetic patients.

Question

Quizplus · Accepted Answer

The most common method of producing human insulin in bacteria is through genetic engineering. The human insulin gene is inserted into the bacterium's genome using recombinant DNA technology. Bacteria are able to translate the genetic code of the human insulin gene into the insulin protein, which can then be harvested and purified for use in insulin therapy. Since the genetic code is nearly universal, the bacterium is able to produce human insulin.
