What does viral genome mean?

In modern molecular biology and genetics, the genome is the entirety of an organism 's hereditary information. It is encoded either in DNA or, for many types of virus, in RNA. A virus has either DNA or RNA genes and is called a DNA virus or a RNA virus.

What is the function of viral genome?

The main function of the virion is to deliver its DNA or RNA genome into the host cell so that the genome can be expressed (transcribed and translated) by the host cell. The viral genome, often with associated basic proteins, is packaged inside a symmetric protein capsid.
