The virus may remain latent for long periods of time before initiating a lytic cycle. The problem with this type of cycle is that the viral nucleic acid that becomes integrated into the host cell's chromosome gets replicated along with the host cell's chromosome and is passed to daughter cells during cell division. Released virions cannot infect cells that are carrying the same prophage - it makes the cell immune to attack by a virion of the same phage. Genus names end in virus - species names are English words. This solved the problem of viral specificity.
Physicians rely on symptoms to diagnose most viral illnesses.
Viral infections sometimes affect human cells in ways that can be seen under the microscope. Some virus-infected cells can be id. because they contain inclusion bodies , collections of viral components such as capsids and nucleic acid, waiting to be assembled into new viral particles. Viral Synthesis - The specifics of this process depend on which of the 5 types of nucleic acids is present in the virus. Maturation - Assembly not really understood 6. Viruses that kill the host cell by causing lysis are called cytocidal .
