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

Molecular models of two different substances are shown below. in the molecule on the left, the oxygen atom pulls on electrons more strongly than the hydrogen atoms. in the molecule on the right, the two oxygen atoms pull on the shared electrons with the same strength. water molecule, h,o oxygen molecule, oz when the two substances are put in the same container, they do not attract each other. why does this happen? a. they both contain oxygen. b. one is polar and one is nonpolar. c . they are both polar. d. they contain different elements.
