Expression vectors are different from other vectors because they contain
A) drug-resistance markers.
B) telomeres.
C) regulatory regions that permit the cloned DNA to produce a gene product.
D) DNA origins.
E) reporter genes that are expressed in the host.

Question

Quizplus · Accepted Answer

Expression vectors contain regulatory regions such as promoters and enhancers that enable cloned DNA to produce a desired gene product. The other options (drug-resistance markers, telomeres, DNA origins, and reporter genes) may be present in expression vectors, but are not unique to expression vectors.
