Question

match the letter to correctly label each viral structur
virus
particles
protein capsid
nucleic acids
protein surface
markers
lipid envelope

Explanation:

• A - Protein Capsid: The protein capsid is the outer shell of a virus that protects the genetic material. In the diagram, it forms the structural boundary around the virus particle.
• B - Nucleic Acids: Nucleic acids (DNA or RNA) are the genetic material of the virus. They are located inside the protein capsid as shown in the diagram.
• C - Protein Surface Markers: These are proteins on the surface of the virus (often part of the capsid or envelope) that help the virus recognize and attach to host cells.
• D - Lipid Envelope: Some viruses have a lipid envelope, which is a membrane - like structure (derived from the host cell in many cases). It is shown as an outer layer in the right - hand virus diagram.

Answer:

A. Protein Capsid, B. Nucleic Acids, C. Protein Surface Markers, D. Lipid Envelope
