|
|
A virus attaches to the surface of a host cell
|
|
|
The proteins and genetic material start to assemble in the cell
|
|
|
The host cell bursts open, releasing the new viruses
|
|
|
The virus injects its genetic material into the cell
|
Detailed explanation-1: -The final stage of replication is assembly and release of new virus particles. Assembly of virus particles involves the association of replicated nucleic acid with newly synthesized capsomeres to form a new nucleocapsid. This may take place in the cytoplasm or in the nucleus of the host cell.
Detailed explanation-2: -Egress. The last stage of viral replication is the release of the new virions produced in the host organism. They are then able to infect adjacent cells and repeat the replication cycle.
Detailed explanation-3: -The viral life cycle can be divided into several major stages: attachment, entry, uncoating, replication, maturation, and release.
Detailed explanation-4: -Step 1: Attachment: The virus attaches itself to the target cell. Step 2: Penetration: The virus is brought into the target cell. Step 3: Uncoating and Replication: The enveloped virus loses its envelope, and viral RNA is released into the nucleus, where it is replicated. Step 4: Assembly: Viral proteins are assembled.
Detailed explanation-5: -Attachment. Penetration. Uncoating. Replication. Assembly. Maturation. Release.
