There is only one well-studied example in which a double-stranded DNA virus does not replicate within the nucleus. This is the Poxvirus family, which comprises highly pathogenic viruses that … Viral replication is the formation of biological viruses during the infection process in the target host cells. Viruses must first get into the cell before viral replication can occur. Through the generation of abundant copies of its genome and packaging these copies, the virus continues infecting new hosts. Replication … See more Viruses multiply only in living cells. The host cell must provide the energy and synthetic machinery and the low- molecular-weight precursors for the synthesis of viral proteins and nucleic acids.

WebApr 3, 2024 · Viruses are “not really living organisms—they can’t carry out on their own any of the functions that we consider to be connected with life.” With a virus like HIV, it becomes very genetically diverse during infection of an individual, because HIV can replicate over and over again about once a day in an individual for years. WebFor the minus-strand DNA viruses, the genome can be used directly to produce mRNA but a complementary copy will still need to be made, to serve as a template for viral genome copies. ssDNA.
