NEET BIOLOGY

Detailed explanation-1: -An array of small holes or pores in the nuclear membrane permits the selective passage of certain materials, such as nucleic acids and proteins, between the nucleus and cytoplasm.

Detailed explanation-2: -The nuclear envelope has many nuclear pores that allow materials to move between the cytosol and the nucleus. Intermediate filament proteins called lamins form a structure called the nuclear lamina on the inner aspect of the inner nuclear membrane and give structural support to the nucleus.

Detailed explanation-3: -The nuclear envelope is a double-layered membrane that encloses the contents of the nucleus during most of the cell’s lifecycle.

Detailed explanation-4: -In eukaryotic organisms, the genetic material is well enclosed by a distinct nuclear membrane and is said to be a true nucleus.

Detailed explanation-5: -The part of the cell that lets things in and out is the cell membrane, also known as the plasma membrane. The cell membrane is a flexible barrier made of a double layer of phospholipids.
