Here’s a 3D model description of coronavirus (SARS-CoV-2):

Shape: The virus is roughly spherical.

Surface: Covered with distinctive spike (S) glycoproteins that stick out like club-shaped projections. These give the virus its crown or corona-like appearance.

Size: About 80–120 nanometers in diameter (not visible to the naked eye, only under an electron microscope).

Structure Details:

Spike proteins (S): Tall protrusions responsible for attaching to host cells.

Envelope (E): A lipid bilayer that surrounds the viral RNA genome.

Membrane proteins (M): Embedded in the envelope, helping maintain the virus’s shape.

Nucleocapsid (N): Protein shell inside the envelope that holds and protects the RNA.

In a 3D model, the virus typically appears as a ball with red spikes protruding outward, while the inner layer shows the RNA genome wrapped with nucleocapsid proteins.
