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.
How are the end results of transcription different from the end results of replication. A cell may need hundreds or thousands of copies of certain proteins or the rRNA and tRNA molecules needed to make proteins. Transcription enables a cell to adjust to changing demands by making a single-stranded complement of only a segment of DNA and only when the particular segment is needed. Many RNA molecules can be transcribed from as single gene at the same time
