RNA and protein data for the viruses analyzed in this work. The number of protein copies per virion varies, even within a single species (Neuman et al., 2011, 2006). For example, the number of spike protein trimers can vary between 50 and 100 per virion. The average number is 74 trimers, giving 74 × 3 = 222 spike proteins in total (Neuman et al., 2011, 2006).
