What is the nuclear membrane made of?
phospholipid bilayer
Assorted References. The nuclear envelope is a double membrane composed of an outer and an inner phospholipid bilayer. The thin space between the two layers connects with the lumen of the rough endoplasmic reticulum (RER), and the outer layer is an extension of the outer…
Is RER connected to outer nuclear membrane?
The nucleus is surrounded by a system of two concentric membranes, called the inner and outer nuclear membranes. The outer nuclear membrane is continuous with the endoplasmic reticulum, so the space between the inner and outer nuclear membranes is directly connected with the lumen of the endoplasmic reticulum.
Which cell organelle helps in derivation of nuclear envelope?
Basically, an endoplasmic reticulum is a plasma membrane found inside the cell that folds in on itself to create an internal space known as the lumen. This lumen is actually continuous with the perinuclear space, so we know the endoplasmic reticulum is attached to the nuclear envelope.
What is true about nuclear membrane composed of?
A nuclear membrane is composed up of two membranes – an inner and an outer membrane. Both membranes consist of phospholipids that are organized in a bilayer. The complete nuclear membrane includes four series of phospholipids. The perinuclear space separates the outer and inner membrane.
What is an analogy for nuclear membrane?

Which of the following organelles has a continuous connection with nuclear membrane RER or ser?
The answer is C)RER (Rough endoplasmic reticulum). It gives a rough granular appearance under the electron microscope. They are extensive and continuous with the outer membrane of the nucleus.
Is nuclear envelope and nuclear membrane same?
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.
How does the membrane differ from the nuclear membrane?
The key difference between the cell membrane and nuclear membrane is that cell membrane encloses the cytoplasm and the cell organelles and is a lipid bilayer while nuclear membrane encloses the nucleus and it is made up of double lipid bilayer.
What is the structure of nuclear membrane?
The nuclear envelope is composed of two concentric lipid bilayer membranes separated by an intermembrane space of about 20-40 nm. The outer membrane is continuous in many places with the rough endoplasmic reticulum. Like the rough ER the outer membrane of the nuclear envelope is dotted with ribosomes.
What are the cell membrane and mitochondria analogous to?
The inner membrane encloses an area called the stoma, which is analogous to the matrix in mitochondria and houses DNA, RNA, ribosomes, and different enzymes.
How does the nuclear membrane differ from the plasma membrane?
The nuclear membrane is distinct from the plasma membrane as shown in a much lower cholesterol-phospholipid ratio, in a higher content in protein, and a certain amount of DNA remaining firmly attached to it.
What is the nuclear membrane of endoplasmic reticulum?
Rough endoplasmic reticulum. A nuclear membrane, also known as the nuclear envelope, nucleolemma or karyotheca, is the double lipid bilayer membrane which surrounds the genetic material and nucleolus in eukaryotic cells. The nuclear membrane consists of two lipid bilayers – the inner nuclear membrane, and the outer nuclear membrane.
What is the nuclear membrane made up of?
The nuclear membrane consists of two lipid bilayers – the inner nuclear membrane, and the outer nuclear membrane. The space between the membranes is called the perinuclear space, a region contiguous with the lumen (inside) of the endoplasmic reticulum.
Which is a derivation of the nuclear envelope?
>> Nuclear envelope is a deriv… Microtubules. Rough endoplasmic reticulum. Smooth endoplasmic reticulum. Membrane of Golgi complex. Rough endoplasmic reticulum.
What is the difference between smooth endoplasmic reticulum and rough ER?
When ribosomes attach to the surface of an ER, it gives a characteristic rough appearance, hence it is called Rough ER. On the other hand, a smooth ER does not have ribosomes on its surface. The other major difference between Smooth Endoplasmic Reticulum And Rough Endoplasmic Reticulum are summarized below:
