If a foreign gene is cloned into a host, it is important that the cloned host itself
A) repress the genetic expression being studied.
B) not produce the protein being studied.
C) produce signal proteins to tag the host protein.
D) produce the protein in larger amounts than the vector.

Question

Quizplus · Accepted Answer

If a foreign gene is cloned into a host, it is important that the cloned host does not produce the protein being studied as this could interfere with the analysis of the protein's function. The goal of cloning a foreign gene into a host is to produce large amounts of the protein of interest. Therefore, D is incorrect. Repressing the genetic expression (A) or producing signal proteins (C) are not necessary requirements for successful cloning, and therefore incorrect.
