Question

The interphase nucleus is enclosed in

• A. A non-porous double membrane
• B. A non-porous single membrane
• C. A porous double membrane
• D. Many membranes

Answer 1

Answer: (C)

A porous double membrane

As we know that the structure and function of nuclear membrane is:-A nuclear membrane is a double membrane that encloses the cell genetic material and nucleoplasm. 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.

As the Interphase is the previous stage of Prophase of the cell cycle and dissolution of nuclear membrane marks the end of prophase, the structure of the nuclear membrane has to be A Porous Double Membrane.

So, the correct option is 'C'
