Three major types of RNA are physically brought together during

Options

A. Replication of DNA
B. Autocatalysis of DNA
C. Translation
D. Transcription

Answer

To solve the question regarding the process during which the three major types of RNA are physically brought together, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Types of RNA**:
The three major types of RNA involved in protein synthesis are:
- **tRNA (transfer RNA)**: Responsible for bringing amino acids to the ribosome during protein synthesis.
- **mRNA (messenger RNA)**: Carries the genetic information from DNA to the ribosome.
- **rRNA (ribosomal RNA)**: A component of the ribosome that helps facilitate the translation process.

2. **Understand the Processes**:
- **Replication of DNA**: This process involves copying DNA and does not involve the three types of RNA coming together.
- **Autocatalysis of DNA**: This is not a standard biological process related to RNA.
- **Transcription**: This is the process of synthesizing RNA from a DNA template, primarily involving mRNA, but does not bring all three types of RNA together.
- **Translation**: This is the process where the mRNA is translated into a protein, and during this process, tRNA, mRNA, and rRNA work together in the ribosome.

3. **Determine the Correct Answer**:
Since the question asks when the three types of RNA are physically brought together, the correct answer is during **translation**. This is the only process among the options provided where all three types of RNA interact.

### Final Answer:
The three major types of RNA are physically brought together during **translation**.
