Question

A new virus with a similar genetic makeup to the Zika virus is found. Although the introductory passage does not describe the Zika virus life cycle in detail, it describes information about other viruses in the same Baltimore class. Based on your knowledge of other viral life cycles and the information provided in the introductory passage, which of the following do you think describes the Zika virus life cycle?

RNA replicase is used to replicate the RNA genome. The RNA genome may be transcribed directly. Polyproteins are cut by proteases to form functional products. Reverse transcriptase is used to make a DNA copy of the genome. The DNA is then replicated and transcribed to make viral products. Polyproteins are cut by proteases to form functional products. The RNA genome must be copied to make a complementary strand that can be transcribed. It is replicated through a DNA intermediate. RNA replicase is used to replicate the RNA genome. The RNA genome may be copied to make a complementary strand that can be transcribed. Polyproteins are not used.
