Ultrastructure of Nucleus 🟦 Introduction A Nucleus is made up of 4 part *Nuclear membrane or karyotheca *Nucleolus *Nuclear sap or nucleoplasm *Chromatin reticulum or nuclear reticulum 🟦 Nuclear membrane or karyotheca *Karyotheca is a bilayered membrane that surrounded nucleus 🟡 structure- 1)made up of lipoprotein 2) this is the trilaminar membrane 3) diameter 62-90 Å 4) distance between to memories 100-500 Å 5) intermediate space between two membrane is called perinuclear cisternae or perinuclear space. 6) the pores presentation nuclear membrane called nuclear pores 7) diameter of the pores 300-500 Å 8) ribosome and endoplasmic reticulum is is attached to it outer membrane of the nuclear membrane 🟡 Nuclear pore- ~nuclear pore is a complex structure. ~part of the pore is diaphragm, septum, plug or nucleoplasmin and various annuli. ~annulus is a circular part that covers the nuclear pores. ~a pore with annulus called pore complex. ~so
