Molecular Virology

The viral genome contains all the information needed to initiate and complete the cycle of infection within a sensitive and tolerant host cell. The infection cycle involves attachment and invasion, viral mRNA and protein production, genomic replication, and finally the assembly and release of new particles. The viral genome encodes from just one protein to over 100 proteins. What is present in the mature viral particles virions is also known as structural proteins. By comparison, the viral genome involved in the assembly, replication, and modification of the host's innate response to infection is called a nonstructural protein. Virtually all DNA viruses that infect humans and animals contain double-stranded DNA. The exceptions are the parvoviridae (parvovirus B19, adeno-associated virus, etc.) and the circovirus family, which includes transfusion transmitted (TT) viruses that may be associated with the development of some cases of hepatitis.
