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.
Viruses codetheir genes on a single type of nucleic acid, either DNA orRNA, but viruses lack ribosomes and the enzymes neces-sary for protein synthesis. Viruses are able to reproduce be-cause their genes are translated into proteins by the cellâsgenetic machinery.he first virus to be isolatedproved to consist of two chemicals, one a protein and theother a nucleic acid. The Nature of Viruses. Viruses occur in all organisms.Able to reproduce only within living cells, viruses are notthemselves alive.
