Nuclear pore

Nuclear pore

(Science: cell biology) openings in the nuclear envelope, diameter about 10 nm, through which molecules (such as nuclear proteins synthesised in the cytoplasm) and rna must pass. Pores are generated by a large protein assembly. Perforations in the [[ Nuclear membrane which allow select materials to flow in and out.
