The ONM-INM connection creates several unique features: a double bilayer structure, a Both I and The endoplasmic reticulum. The nuclear envelope (NE) represents the boundary of the interphase nucleus. 1.The outer membrane of the nucleus is continuous with the membrane of which other organelle? What is bound membrane? The ONM continuously connects to the ER, and its surface, like that of the ER, is decorated with ribosomes. The Eukaryotic cells contain membrane-bound organelles meaning that these organelles (e.g. The nucleus is surrounded by a system of two concentric membranes, called the inner and outer nuclear membranes. The outer membrane of the nucleus is continuous with the membrane of which other organelle? Only I is correct 2. It is composted of two morphologically distinct parallel membranes, the inner and outer nuclear membranes, enclosing a perinuclear space (Figure 1 ).

The outer nuclear membrane is the outermost barrier of the nucleus. The outer nuclear membrane is continuous with the membrane of the rough endoplasmic reticulum (rough ER). This membrane is studded with ribosomes that participate in protein synthesis. Nuclear outer membrane is in continuous with Endoplasmic Reticulum. The inner nuclear membrane is connected with the fibers like nuclear lamina or honeycomb layer or nuclear cortex (made up of proteins). The nuclear envelope has a complex structure consisting of two nuclear membranes an underlying nuclear lamina and nuclear pore complexes (Figure 8.1). It serves to separate the chromosomes from the rest of the cell. The membrane facing the cytoplasm is termed the outer nuclear membrane (ONM), and the membrane facing the The outer membrane of the nucleus usually remains continuous with the endoplasmic reticulum and also bears ribosomes on it. The nuclear membrane is a double-layered structure that encloses the contents of the nucleus. What is the outer nuclear membrane? A. This membrane protects the nuclear material. The outer membrane of the nucleus: I. is continuous with the Endoplasmic reticulum II. The nuclear membrane surrounds the nucleus of the cell. Like the cell membrane, the nuclear membrane is a lipid bilayer, meaning that it consists of two layers of lipid molecules. The outer layer of lipids has ribosomes, structures that make proteins, on its surface. The nucleus is surrounded by a system of two concentric membranes called the inner and outer nuclear membranes. The reason the nucleus has two membranes is another. The nuclear envelope also known as the nuclear membrane is made up of two lipid bilayer membranes that in eukaryotic cells surrounds the nucleus which encases the genetic material.
