The dolphins comprise the extant families Delphinidae (the oceanic dolphins), Platanistidae (the Indian river dolphins), Iniidae (the new world river dolphins), and Pontoporiidae (the brackish dolphins), and the extinct Lipotidae (baiji or Chinese river dolphin).
The answer should be C. Once the host cell transcribes a viral gene, the RNA is formed. The RNA is then translated in order to give us the viral proteins essential for the replication of the virus So the answer is when a cell transcribes a viral gene, the host cell then translates it.
The viruses that show lytic cycle, first enter a cell, replicate and then cause the cell to burst releasing new viruses. What happens here is, the virus injects its nucleic acids (DNA or RNA) into the host cell and next that particular gene takes over the metabolic activities of the host cell.
