Question: How does a DNA virus use more energy than a RNA virus?



Replies:
It takes a lot more biochemical machinery to build DNA molecules than it does RNA. The simple energetics of DNA molecules are more intensive than RNA, and perhaps more importantly, the mechanisms for DNA transcription are contained primarily in the nucleus, so a DNA virus must infiltrate further into the cell. An RNA virus has more location options than a DNA virus. Either way you slice it, the RNA virus has an easier road to replication (although the DNA virus has an advantage in persistence).

Hope this helps, Burr
