Description of the different MS2 subpopulations and their respective ratios, based on (Armanious et al., 2016a). MRNA-virion, MRNA-free viron, MRNA, and Mcapsid are the masses of an individual virion containing RNA, an individual virion without RNA, the RNA, and the protein capsid, respectively. RNA-virions and RNA-free virions refer to individual virions with and without RNA in the assembled capsid.
