Kuttalle nucleus bekkamo ta’an nuclear envelope fi nuclear lamina dha. Nuclear envelopen membrane daballata (membrane lama) kan organelleotta hunda ofii kessatti marsee, wantotta nucleus kessatti argaman kan cytoplasm irra gargar bassu dha. Nuclear laminan immo waan walitti xaxame yoo ta’u jabbena akkumma cytoskeleton celli kennu innillen nucleus kenna. Nuclear membranen moleculotta bayye waan hin dabarsineef (impermeable membrane waan ta’ef) demma moleculotta nucleus fi cytoplasma jiddu akka jirrattu urran nucleus (nuclear pore)n jirrachun barbachisaa.
