In addition to free SV40 minichromosomes in the compact form, complete virions were obtained from the nuclear extract of productively infected cells. Capsid proteins VP1, VP2, and VP3, as well as histones, were observed on electrophoregrams of proteins prepared from virions. In contrast to the widely accepted view, histone H1 was found in virions in stoichiometric amounts with respect to other histones. The same is true for virions isolated by a conventional method. Free minichromosomes present in infected cells contain all histones and practically no viral proteins.
