Host cellHost nucleolusHost nucleus


The host nucleolus is a dark, dense, roughly spherical area of fibers and granules in the host nucleus. Only plant and animal nuclei contain one or more nucleoli, although some do not. No membrane separates the host nucleolus from the host nucleoplasm. It mediates ribosomal RNA biogenesis.
