Which event occurs first during viral infection? the viral genome and proteins enter the host cell. the virus fuses its envelope to the host cell membrane. the viral genome is transcribed. viral proteins and mrna molecules are assembled?

In the list provided above, the event which occurs first during viral infection is that the virus fuses its envelope to the host cell membrane. This is followed sequentially by the following steps: the viral genome and proteins enter the host cell, viral proteins and mRNA molecules are assembled, and the viral genome is transcribed.
