Virus

Generic standalone virion in clean scientific textbook clipart style, shown as a tiny noncellular infectious particle much smaller than a cell. The particle is compact and symmetrical, typically with a faceted icosahedral or slightly polyhedral capsid, though some generic versions may appear smoothly spherical. A distinct outer protein shell encloses a central core of genetic material shown as a compact mass or visible coiled RNA or DNA strand in contrasting color. In some versions a thin spherical membranous envelope surrounds the capsid, with small evenly spaced surface spikes projecting outward; in non-enveloped versions the surface is smooth. The overall appearance is a crisp textbook icon with bold clean outlines, clear geometric boundaries, strong symmetry, and simple scientific colors such as pale blue, gray, purple, green, red, teal, or gray-blue. No tail structures or cellular organelles are present.
