Hit Viruses

How viruses use a host cell to replicate

1. Invade cell
proteins on the surface of the virus bind to receptors on the host cell. The virus fuses with the cell.

2. Uncoat
Human enzymes dissolve the virus's protein coat, releasing the genes in its core.

3. Multiply
The virus takes over the host cell's machinery to make copies of its genes and proteins

4. Go forth
the genes and the proteins form new viruses, which bud from the cell. and seek new hosts
