The correct Answer is:
### Step-by-Step Solution: 1. **Understanding the Question**: The question asks about the mechanism responsible for the transport of RNA and proteins from the nucleus to the cytoplasm. 2. **Identifying Key Components**: The nucleus is the cellular organelle where RNA is synthesized. The cytoplasm is where proteins are synthesized and where various cellular processes occur. 3. **Role of RNA**: RNA (ribonucleic acid) is crucial for gene expression and is produced in the nucleus. Different types of RNA (such as mRNA, tRNA, and rRNA) are generated during transcription. 4. **Transport Mechanism**: The transport of RNA and proteins from the nucleus to the cytoplasm is facilitated by specialized structures known as nuclear pore complexes. 5. **Nuclear Pore Complexes**: These are large protein complexes that span the nuclear envelope. They serve as gateways that regulate the movement of molecules between the nucleus and the cytoplasm. 6. **Export Receptors**: Mobile export receptors play a significant role in recognizing and binding to RNA and proteins that need to be transported out of the nucleus. 7. **Conclusion**: Therefore, the transport of RNA and protein through the nucleus to the cytoplasm is primarily carried out by the nuclear pore complexes. ### Final Answer: The transport of RNA and protein through the nucleus to the cytoplasm is carried out by the nuclear pore complexes. ---
