A) It is in the common N terminal domain, which is the large surface protein region.
B) It is in the common C terminal domain, which is the small surface protein domain.
C) The surface antigens have a myristate attached to the large protein domain.
D) The transmembrane alpha helices are found in the middle antigen region of the protein.
E) It is located in a beta-barrel structure found in the large surface antigen.
