Question

How does the virus infect the cells and replicates itself

Answer 1

Viruses depend on the host cells that they infect to reproduce. ... When it comes into contact with a host cell, a virus can insert its genetic material into its host, literally taking over the host's functions. An infected cell produces more viralprotein and genetic material instead of its usual products.
During uncoating, replication, and assembly, theviral DNA or RNA incorporates itself into the host cell's genetic material and induces it to replicate the viral genome
