Explanation / Answer

Ans. The correct order for an animal virus life cycle is:

Attatchment-> entry -> replication -> assembly ->budding

1.) first of all the virus gets attached to the cell membrane with the help of receptors present in the cell membrane which are specific to the configuration of a virus. They get attached like a lock and key.

2.) Entry: the virus gets fused with the host cell membrane and results in endocytosis.

3.) Replication: The nucleic acid of virus takes over the metabolic machinery of the host. The virus enters the nucleus of the host cell and starts replication.

4.) Assembly: There is disassociation of a capsid in the cytoplasm to allow the replication of viral DNA or RNA. Spike of the virus is inserted in the host cell membrane.

5.) Budding: The enveloped virus gets released by budding.
