About Viral Genetics

Viral genetics is study of heritable genes present in the particular which responsible for the viral infection such as genome structure replication and some protein which play important role in the viral pathogenesis.

Viruses are continuously changing as a result of genetic selection. They undergo subtle genetic changes through mutation and major genetic changes through recombination. Mutation occurs when an error is incorporated in the viral genome. Recombination occurs when coinfecting viruses exchange genetic information, creating a novel virus
