Cis face of golgi cisternae is always

Options

A. Nearer to the nucleus
B. Nearer to the nucleolus
C. Away from the nucleus
D. Away from the nucleus

Answer

To answer the question "Cis face of Golgi cisternae is always," we need to analyze the structure and orientation of the Golgi apparatus. Here’s a step-by-step solution:

### Step-by-Step Solution:

1. **Understanding the Golgi Apparatus**:
- The Golgi apparatus consists of a series of flattened membrane-bound sacs known as cisternae. It plays a crucial role in the modification, sorting, and packaging of proteins and lipids.

2. **Identifying the Two Faces**:
- The Golgi apparatus has two distinct faces: the **cis face** and the **trans face**.
- The **cis face** is the side that receives materials from the endoplasmic reticulum (ER), while the **trans face** is the side that dispatches materials to other locations in the cell.

3. **Orientation of the Faces**:
- The cis face is typically oriented towards the nucleus of the cell. This is because it is the entry point for materials coming from the ER, which is also located near the nucleus.
- The trans face, on the other hand, is oriented away from the nucleus and is involved in the export of processed materials.

4. **Conclusion**:
- Based on the orientation of the Golgi apparatus, we can conclude that the cis face of the Golgi cisternae is always **nearer to the nucleus**.

### Final Answer:
The cis face of Golgi cisternae is always **nearer to the nucleus**.
