Question #b788d
1 Answer
Viruses are specific to their host cell because of the attachment sites called receptors (specific protein molecules) that the virus can recognise.
Explanation:
Viruses are considered non-living because they cannot replicate on their own; they need a host cell in order to replicate. Most viruses require specific hosts in order to replicate since they recognise receptors on the host cell surface that allow the virus to bind to the host cell (the first step of viral replication).
In the second step, the virus penetrates the cell wall and injects its genetic material into the host cell.
In the third step, the viral RNA/DNA takes over the cell's replicating machinery and produces multiple copies of itself.
In the fourth step, the protein coats are now synthesised using material of the host cell.
In the fifth step, the protein coats and viral genetic material are assembled.
In the sixth step, the host cell is ruptured, releasing the mature viral particles.
