The structure of nuclear membrane facilitates

Options

A. Organization of the spindle
B. Synapsis of homologous chromosome
C. Nucleo-cytoplasmic exchange of material
D. Anaphasic separation of daughter chromosome

Answer

**Step-by-Step Solution:**

1. **Understanding the Nuclear Membrane**: The nuclear membrane, also known as the nuclear envelope, is a double-layered membrane that surrounds the nucleus in eukaryotic cells. It consists of an outer membrane and an inner membrane.

2. **Function of the Nuclear Membrane**: The primary function of the nuclear membrane is to protect the genetic material (DNA) contained within the nucleus. It acts as a barrier that separates the contents of the nucleus from the cytoplasm.

3. **Presence of Nuclear Pores**: The nuclear membrane is not completely solid; it contains nuclear pores. These pores are large protein complexes that span the nuclear envelope and allow for the regulated exchange of materials between the nucleus and the cytoplasm.

4. **Nucleocytoplasmic Exchange**: The nuclear pores facilitate the movement of molecules such as RNA and proteins. This process is known as nucleocytoplasmic exchange. It is essential for various cellular functions, including gene expression and the synthesis of proteins.

5. **Conclusion**: Based on the structure and function of the nuclear membrane, it primarily facilitates the nucleocytoplasmic exchange of materials. Therefore, the correct answer to the question is that the structure of the nuclear membrane facilitates nucleocytoplasmic exchange of material.
