Question

choose the correct term for each lettered box to complete this concept map. life cycle of an enveloped animal virus

Explanation:

To solve this, we analyze the life cycle of an enveloped animal virus:

Step 1: Identify Process for “L”

The virus attaches to host cell receptors (matches “Targets receptors on specific host cells”). So \( L = \text{Attachment} \).

Step 2: Process “B” (After Attachment)

After attachment, the virus enters the host cell (e.g., via endocytosis or membrane fusion). So \( B = \text{Entry} \).

Step 3: Process “C” (After Entry)

Post - entry, the virus uncoats (releases genetic material from the capsid/envelope). So \( C = \text{Uncoating} \).

Step 4: Process “D” (After Uncoating)

Uncoating leads to viral genome replication (copying viral nucleic acid). So \( D = \text{Viral Genome Replication} \).

Step 5: Process “E” (Parallel to Genome Replication)

Simultaneously, viral protein synthesis occurs (making capsid, envelope proteins). So \( E = \text{Viral Protein Synthesis} \).

Step 6: Process “F” (After Genome/Protein Synthesis)

Genome and proteins assemble into new virions (viral particles). So \( F = \text{Viral Assembly} \).

Step 7: Process “H” (After Assembly)

New virions exit the host cell (e.g., budding for enveloped viruses). So \( H = \text{Release} \).

Step 8: Process “A” (Overall Cycle)

The entire cycle starts with a virion (mature virus particle) targeting the host. So \( A = \text{Virion} \).

Step 9: Process “G” (for dsDNA Viruses)

For dsDNA viruses, the genome can integrate into the host genome (Latency) or follow lytic replication. If focusing on integration, \( G = \text{Latency (Integration into Host Genome)} \).

Final Answers (Key Boxes):

• \( A \): Virion
• \( B \): Entry
• \( C \): Uncoating
• \( D \): Viral Genome Replication
• \( E \): Viral Protein Synthesis
• \( F \): Viral Assembly
• \( H \): Release
• \( L \): Attachment
• \( G \) (for dsDNA): Latency (or Integration)

(Adjust based on standard virus life - cycle terminology; e.g., “Latency” for persistent infections, or “Lytic Cycle” steps. The core processes are attachment, entry, uncoating, replication, synthesis, assembly, release, with the virion initiating the cycle.)
