Viruses function by reproducing. However, in the real sense they do not really reproduce, but multiply. The virus structure is made in a way that allows it to replicate itself, thus creating numerous viruses. This is the reason why many will refer to the process as reproduction.here are two main ways that viruses reproduce or multiply and these are listed below. 1  Lytic Cycle: With the lytic cycle, the virus attaches itself to a host cell and infuses the cell with its nucleic acid.
A virus is a small parasite that cannot reproduce by itself. Once it infects a susceptible cell, however, a virus can direct the cell machinery to produce more viruses. Most viruses have either RNA or DNA as their genetic material.hat are central to the life cycle of a virus are the types of nucleic acids formed during its replication and the pathway by which mRNA is produced. The relation between the viral mRNA and the nucleic acid of the infectious particle is the basis of a simple means of classifying viruses.
