This egg actually has a lot of detail about the coronavirus (SARS-Cov-2) including representation of the plus sense RNA wound around the nucleocapsid protein in the center of each virion, and the envelope and the membrane (with a transporter protein added as a separate color, and all the thickly placed spike proteins (S1 and S2). What it lacks, aside from being a polymer clay model, a slice through the center of a pretend virion, it does lack the hemagglutinin esterase spike proteins. So sorry for missing that. LOL. You can purchase this egg, or one made similarly, here, by searching the products on this blog, or at this website called memory-beads.
