2015, VirologyCitation Excerpt :Closed circles (spheres) are called immature virions (IV). Probably all IV contain DNA condensed in a spherical “nucleoid” structure, however because the nucleoid is acentric it is visible in only some sections of the IV, called IVN (IV with nucleoid) (Morgan et al., 1955). Immature virions contain the majority of the MV membrane proteins and all of the core proteins, and they are coated with a honeycomb matrix of the viral D13 protein, which serves as a membrane scaffold during assembly of IV (Heuser, 2005; Szajner et al., 2005).
In A Nutshell: Structure and Assembly of the Vaccinia Virion
2006, Advances in Virus ResearchCitation Excerpt :One of the unresolved questions is whether genome entry precedes closure of the IV membrane. Serial section analysis shows that most fully closed IV do indeed have nucleoids (Morgan et al., 1955), suggesting that genome encapsidation is likely to occur prior to the closure of the IV (Morgan, 1976a,b). If this model is not correct, then the encapsidation machinery must either pass through a proteinaceous plug that has been proposed to mark the site of IV membrane closure, or it must pass through the IV membrane itself.
