Virus Particle Cutaway Structure

A dramatic cutaway illustration of a spherical enveloped RNA virus, shown in isometric 3D with one quarter of the outer envelope sliced away to reveal internal layers. The outermost layer is a phospholipid bilayer membrane in translucent coral-pink, studded with spike glycoproteins rendered as club-shaped red protrusions. Beneath it, a matrix protein layer in warm gold forms a geodesic cage. Inside, a nucleocapsid core in deep burgundy contains a tangled RNA genome drawn as a spiralling purple ribbon. A separate exploded-view inset at the lower-left identifies each component with numbered callouts and a legend table. Background: very dark navy gradient to black, giving a Science cover presentation feel. Lighting: soft rim light from upper-right, slight sub-surface scattering on the translucent membrane. Labels in white Helvetica-style, reversed out of the dark background. The image should feel like an editorial scientific rendering used in a virology textbook chapter opener.
