Summary Regardless of their genetic constitution, viral genomes are replicated, expressed, and assembled in association with living host cells. These entities do not undergo division, but rather generate new particles through the assembly of preformed components.

Interestingly, viruses do more than simply mimic host mechanisms like polyadenylation, triple helix structures, and 5′ capping to protect their transcripts from host exonucleases . Cytoplasmic viruses use diverse strategies to overcome the odds and trick the host into ignoring or even, preferentially, stabilizing their transcripts.

In eukaryotic cells, most DNA viruses can replicate inside the nucleus, with an exception observed in the large DNA viruses, such as the poxviruses, that can replicate in the cytoplasm. With a few exceptions, RNA viruses that infect animal cells replicate in the cytoplasm. An important exception that will be highlighted later is Influenza virus.

Virus particles are assembled from these newly synthesized biological molecules and become infectious virions. Finally, the virions are released from the cell to continue the process of infection.

Most viruses have icosahedral or helical capsid structure, although a few have complex virion architecture. An icosahedron is a geometric shape with 20 sides, each composed of an equilateral triangle, and icosahedral viruses increase the number of structural units in each face to expand capsid size.

Positive-strand RNA virus – Wikipedia
Positive-strand RNA viruses ( +ssRNA viruses) are a group of related viruses that have positive-sense, single-stranded genomes made of ribonucleic acid. The positive-sense genome can act as messenger RNA (mRNA) and can be directly translated into viral proteins by the host cell’s ribosomes.

Replication of DNA Viruses. A DNA virus is a virus that has DNA as its genetic material and replicates using a DNA-dependent DNA polymerase. The nucleic acid is usually double-stranded DNA but may also be single-stranded DNA. The DNA of DNA viruses is transcribed into mRNA by the host cell. The viral mRNA is then translated into viral proteins.

Why do RNA viruses recombine? | Nature Reviews Microbiology
RNA viruses are able to undergo two forms of recombination: RNA recombination, which (in principle) can occur in any type of RNA virus, and reassortment, which is restricted to those viruses…

Physical virology: From virus self-assembly to particle mechanics
However, viruses do not always show a clear single PS on their genome driving the assembly; this is particularly valid for spherical ssRNA viruses. Instead, a new strategy has been proposed to explain genome specificity of these viruses, highlighting the active role of the whole viral genome during packaging.

Single-Stranded RNA Virus – an overview | ScienceDirect Topics
Single-Stranded RNA Virus. However, many acute ssRNA viruses encode one or several viral suppressors of RNA silencing (VSR), which inhibits the host RNA silencing system, thus enabling the virus to overcome the host defense system and propagate systemically in the host plant.
