Question

Identify the steps of the lytic cycle.

(label 1-5)



The pieces made in replication are assembled to complete the new virus particles.



The new viral nucleic acid and viral proteins are replicated.



The virus attaches to the host cell.



The original virus releases a protein that causes the cell wall to burst (lysis), killing the cell and releasing viruses.



The hostâs DNA is disassembled and the virus takes over the cellâs metabolic activity

Answer 1

The lytic cycle includes five steps: attachment of the virus to the host cell, penetration of the viral nucleic acid, replication of viral components, assembly of new virions, and release of the viruses through lysis of the host cell.

Step-by-step explanation:

The Lytic Cycle Steps

The lytic cycle is a process by which a virus replicates within a host cell and eventually leads to the cell's destruction. The steps of the lytic cycle are as follows:

1. Attachment: The virus attaches to the host cell by interacting with specific receptors on the cell's surface.
2. Penetration: The viral nucleic acid is injected into the host cell, leaving the capsid outside or bringing the capsid inside if necessary.
3. Replication: The viral nucleic acid takes over the cell's machinery to replicate itself and produce viral proteins.
4. Assembly: Newly synthesized viral components are assembled into complete virions.
5. Release: The host cell is lysed, or burst open, releasing the new virions to infect adjacent cells.

The final result is the destruction of the host cell and the dispersal of new viruses into the environment, ready to infect other cells and repeat the cycle.

Answer 2

These are the steps of the lytic cycle with labels 1-5:

• Attachment
• Entry
• Replication
• Assembly
• Lysis

What are these steps?

Attachment: The virus attaches to the host cell using specific receptors on the cell surface.

Entry: The virus enters the host cell by endocytosis or by injecting its genetic material directly into the cell.

Replication: The viral genome is replicated inside the host cell, using the host cell's machinery.

Assembly: The viral proteins and nucleic acid are assembled into new virus particles.

Lysis: The host cell is lysed (broken open) by viral enzymes, releasing the new virus particles into the environment.
