Select the Nuclear membrane closeup. How is the nuclear membrane similar to the cell membrane? Select the Nuclear membrane closeup. How is the nuclear membrane similar to the cell membrane?
Answer:
A nuclear membrane is a double membrane that encloses the cell nucleus. It serves to separate the chromosomes from the rest of the cell. The nuclear membrane includes an array of small holes or pores that permit the passage of certain materials, such as nucleic acids and proteins, between the nucleus and cytoplasm.
The similarities between nuclear membrane and cell membrane are both are made up of lipid bilayers, main functions of both membranes are protection and transportation, both are extremely important for the cell survival.
What is nuclear membrane?"The nuclear membrane is a double layer that encloses the cell's nucleus, where the chromosomes reside."
What is the other function of nuclear membrane?"The critical function of the nuclear membrane is to act as a barrier that separates the contents of the nucleus from the cytoplasm."
What is cell membrane?"The cell membrane, also called the plasma membrane, is found in all cells and separates the interior of the cell from the outside environment."
What are the other functions of cell membrane?The other functions of the cell membrane include
identification,communication,regulation of solute exchange through the membrane,isolation of the cytoplasm from the external environment.What is lipid bilayers?"The lipid bilayer (or phospholipid bilayer) is a thin polar membrane made of two layers of lipid molecules."
