A distinguishing feature of poxvirus is _____
a. its large size
b. a polyhedral capsid
c. the type of RNA it contains
d. the production of several types of warts

Verified step by step guidance

1. Identify the key characteristics of poxviruses.
2. Consider the structural features of poxviruses, such as their size and shape.
3. Recall that poxviruses are known for their large size compared to other viruses.
4. Understand that poxviruses have a complex structure, not a simple polyhedral capsid.
5. Recognize that poxviruses are DNA viruses, not RNA viruses, and are known for causing skin lesions, not specifically warts.

Key Concepts

Poxvirus Characteristics

Poxviruses are a family of viruses known for their large size compared to other viruses, often measuring 200-400 nanometers in diameter. This size allows them to be visible under a light microscope, which is unusual for viruses. Understanding this characteristic is crucial for distinguishing poxviruses from other viral families.

Viral Structure

Poxviruses possess a unique structure that includes a complex, brick-shaped morphology rather than the typical polyhedral capsid found in many other viruses. This structural difference is significant in identifying poxviruses and understanding their mode of infection and replication.

Viral Genome

Poxviruses contain a double-stranded DNA genome, which is atypical as many viruses have RNA genomes. This DNA structure allows for more complex replication and transcription processes, influencing how poxviruses interact with host cells and their pathogenicity.
