Interphase nucleolus
WebThe interphase nucleus is characterized by a nuclear matrix structure that forms a residual scaffolding network composed of only 10% of the total nuclear proteins. The nuclear matrix contains residual elements of the pore-complex lamina, the nucleolus, and an intranuclear fibrous network. The matrix provides the basic shape and structure of the ... WebMammal cells may contain from 1 to 5 nucleoli. The size of the nucleolus may change along with the cell activity, sometimes becoming larger than 1 µm in diameter. During interphase, several nucleoli may join together to form a larger one. In general, cells having intense protein synthesis show larger nucleoli.
