Which of the following sequences places the steps of viral replication in the correct order? Assume the virus uses DNA as its genetic material.

a. New viral proteins are synthesized by the host cell ribosome, viral DNA is replicated, virus binds to host cell membrane, new viruses assemble and break out of the cell, viral mRNA is transcribed from viral DNA
b. Viral mRNA is transcribed from viral DNA, new viral proteins are synthesized by the host cell ribosome, virus binds to host cell membrane, viral DNA is replicated, new viruses assemble and break out of the cell
c. Virus binds to host cell membrane, viral DNA is replicated, viral mRNA is transcribed from viral DNA, new viral proteins are synthesized by the host cell ribosome, new viruses assemble and break out of the cell
d. Viral mRNA is transcribed from viral DNA, new viral proteins are synthesized by the host cell ribosome, viral DNA is replicated, new viruses assemble and break out of the cell, virus binds to host cell membrane
Viral DNA is replicated, new viruses assemble and break out of the cell, new viral proteins are synthesized by the host cell ribosome, viral mRNA is transcribed from viral DNA, virus binds to host cell membrane


Ans: c. Virus binds to host cell membrane, viral DNA is replicated, viral mRNA is transcribed from viral DNA, new viral proteins are synthesized by the host cell ribosome, new viruses assemble and break out of the cell
