Q: Certain viruses lack 5' caps on their mRNA sequences. Which of the following answers explains one of the ways in which such viruses produce their proteins?
A		They carry their own ribosomes which do not need 5' caps in order to initiate translation
B		They use Internal Ribosomal Entry Sites (IRES) which allow for the assembly of cellular ribosomes to initiate translation
C		They carry out protein synthesis prior to infection; the mRNA is incorporated into the host nucleic acids in dormancy
D		They initiate translation from the 3' polyA tail instead of the 5' cap to avoid the problem.
