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.
Lysogenic Cycle of Bacteriophages. In the lysogenic cycle, after a phage enters its host cell it does not destroy the host's DNA and the phage s genome does not immediately take control of the cell. Instead the viral DNA is inserted into the bacterial chromosome, but virus remains hidden and inactive, allowing the host to reproduce.
