The disease is spread from chimpanzees, who are infected with a very dangerous virus that induces rage. These infected chimps are held captive in a laboratory, but a group of animal activists sets out to liberate them. So, they get infected too, and spread the infection further.
Answer:
C
activates a chemotaxic response in certain phagocytic cells
Antigens determine blood type
An example of a missense mutation in a protein-encoding gene would most likely be a neutral mutation is option B: replacement of a polar amino acid with another polar amino acid at the protein's surface.
A frequent and well-known example of a missense mutation is the blood condition sickle-cell anemia. Missense mutations exist in the DNA at a single location in sickle-cell anemia patients. A different amino acid is required in this missense mutation, which also alters the overall structure of the protein. Similarly, replacement of a polar amino acid by another polar Ami no acid at the protein's surface is a missense mutation causing change in a single site.
A neutral mutation is one whose fixation is unrelated to natural selection. Therefore, the independence of a mutation's fixation from natural selection can be used to define the selective neutrality of a mutation.

Complete question is:
Which example of a missense mutation in a protein-encoding gene would most likely be a neutral mutation?
a) Replacement of a polar amino acid with a nonpolar amino acid at the protein's outer surface
b) Replacement of a polar amino acid with another polar amino acid at the protein's surface
c) Replacement of a polar amino acid with another polar amino acid in the protein's interior
d) Replacement of a polar amino acid with a nonpolar amino acid in the protein's interior
