- The cell is the basic unit of all living things, and viruses which are generally not considered living but have the ability to infect cells. Describe how the structure of a virus compares to the structure of a cell. You should explain (not list) at least two similarities and two differences between features of cells and viruses including a brief explanation of the function of those structures. Explain why viruses need cells.of Poxviruses are unusual among DNA viruses because their replication cycles takes place entirely in the host cell cytoplasm. How can these viruses carry out genome replication and transcription of viral genes without going to the nucleus? Briefly explain.
