Coronavirus Structure Diagram - Viral Anatomy Explained #3866515 (License: Personal Use)

This detailed illustration depicts a coronavirion in cross-section, revealing its outer lipid envelope studded with blue spike (S) glycoproteins, yellow membrane (M) proteins, and smaller envelope (E) proteins. Inside, the helical ribonucleoprotein complex-comprising viral RNA (gray strands) bound to nucleocapsid (N) proteins-is clearly visible. The image emphasizes how structural features enable host cell entry and viral assembly.

Used in educational, medical, or public health web pages explaining virology, pandemic response, or vaccine development; matches user intent for understanding how coronaviruses infect cells and why certain treatments target spike proteins.
