Nucleus controls the activity of cytoplasm by sending :-

Options

A. Enzymes
B. c AMP
C. Hormones
D. RNA

Answer

To answer the question "Nucleus controls the activity of cytoplasm by sending:", we will analyze the options provided and explain the correct answer step by step.

### Step-by-Step Solution:

1. **Understanding the Role of the Nucleus**:
- The nucleus is often referred to as the control center of the cell because it houses the cell's genetic material (DNA). It plays a crucial role in regulating cellular activities.

2. **Function of DNA**:
- The DNA in the nucleus contains the instructions for synthesizing proteins, which are essential for various cellular functions.

3. **Transcription Process**:
- The first step in protein synthesis is transcription, where the DNA is transcribed into messenger RNA (mRNA). This mRNA carries the genetic information from the nucleus to the cytoplasm.

4. **Transport of RNA**:
- The nucleus has nuclear pores that allow the transport of RNA and other macromolecules into the cytoplasm. This transport is essential for the next step in protein synthesis.

5. **Translation Process**:
- Once the mRNA reaches the cytoplasm, it undergoes translation, where ribosomes read the mRNA sequence and synthesize proteins based on that information.

6. **Conclusion**:
- The nucleus controls the activity of the cytoplasm primarily by sending RNA (specifically mRNA), which is crucial for protein synthesis. Therefore, the correct answer to the question is **RNA**.

### Answer:
The nucleus controls the activity of the cytoplasm by sending **RNA**.
