Many drugs are produced by placing human genes into bacteria.The bacteria then transcribe and translate these genes into functional human proteins that can then be purified and given as drugs.The fact that this process works is consistent with which statement?

Question

Quizplus · Accepted Answer

The fact that bacteria are able to produce functional human proteins indicates that humans and bacteria share a common ancestor, and therefore some genetic similarities. This concept is known as homology, and is the basis for many research techniques, including genetic engineering. Option A is incorrect because bacteria do not mimic human cells, but rather use the human gene sequences to produce the desired protein. Option C is incorrect because bacteria are able to survive and reproduce in a variety of environments, and do not need human proteins to live. Option D is incorrect because bacteria are able to divide outside of host cells, and in fact, many bacterial strains are cultured in laboratories without the need for a host. Option E is incorrect because both humans and bacteria use DNA as their genetic material, and the process of transcription and translation is similar in both types of organisms.
