How viruses do this depends mainly on the type of nucleic acid DNA or RNA they contain, which is either one or the other but never both. Viruses cannot function or reproduce outside a cell, and are totally dependent on a host cell to survive. Most viruses are species specific, and related viruses typically only infect a narrow range of plants ...
Virus tropism refers to the virus' preferential site of replication in discrete cell types within an organ. In most cases, tropism is determined by the ability of the viral surface proteins to fuse or bind to surface receptors of specific target cells to establish infection.
A virus is a tiny infectious agent that reproduces inside the cells of living hosts. When infected, the host cell is forced to rapidly produce thousands of identical copies of the original virus. Unlike most living things, viruses do not have cells that divide; new
They lack nuclei but contain other organelles that assist with the replication processes. Viruses are sometimes considered akaryocytes but the suffix "cyte" means cells. Akaryote is also used as a synonym for akaryocyte however 'ote" implies a taxonomic relationship that does not exist among akaryocytes. [1]
A virus is a submicroscopic infectious agent that replicates only inside the living cells of an organism. [1] Viruses infect all life forms, from animals and plants to microorganisms, including bacteria and archaea. [2] [3] Viruses are found in almost every ecosystem on Earth and are the most numerous type of biological entity.
Whether or not viruses should be considered as alive is controversial. [ 33 ] [ 34 ] They are most often considered as just gene coding replicators rather than forms of life. [ 35 ] They have been described as "organisms at the edge of life" [ 36 ] because they possess genes , evolve by natural selection, [ 37 ] [ 38 ] and replicate by making ...

Generally, if a virus kills its host too quickly, the host will not have a chance to come in contact with other hosts and transmit the virus before dying. In serial passage, when a virus was being transmitted from host to host regardless of its virulence, such as Subbaro's experiment, the viruses that grow the fastest (and are therefore the ...
