MICROANATOMY

Detailed explanation-1: -Like other cell membranes, the nuclear membranes are phospholipid bilayers, which are permeable only to small nonpolar molecules (see Figure 2.49). Other molecules are unable to diffuse through the phospholipid bilayer.

Detailed explanation-2: -Nuclear membrane is the structure that encloses and surrounds the nucleus. Similar to the cell membrane, it is made up of phospholipid bilayer which renders its semi-permeability.

Detailed explanation-3: -The nuclear envelope, also known as the nuclear membrane, is made up of two lipid bilayer membranes that in eukaryotic cells surround the nucleus, which encloses the genetic material.
