7.) Have different shapes (Polyhedral, Spherical, Helical and complex)

Question 5

What are the steps of virus reproduction?

Answer 5

Adsorption
Penetration
Latent
Lysis

Question 6

Explain the reproduction of viruses.

Answer 6

Adsorption: Attached itself to host cell
Penetration: Injects DNA or RNA into host cell.
Latent: Replicates/copies it’s viral DNA using host cells DNA. Makes capsids from the contents of the host cell for each new virus and many new viruses are produced.
Lysis: Host cell bursts to release new viruses and the host cell dies.
