tRNA is found in

Options

A. nucleus
B. cytoplasm
C. membranes
D. mitochondria

Answer

**Step-by-Step Text Solution:**

1. **Understanding tRNA**: tRNA stands for transfer RNA. It plays a crucial role in the process of translation, where it helps in decoding the mRNA (messenger RNA) to synthesize proteins.

2. **Identifying Locations**: The question asks where tRNA is found. We need to analyze the options provided:
- **Nucleus**: This is the control center of the cell, where DNA is stored and RNA is synthesized.
- **Cytoplasm**: This is the semi-solid matrix of the cell where various cellular activities occur, including protein synthesis.
- **Membranes**: These are structures that surround the cell and organelles, but they do not contain tRNA.
- **Mitochondria**: Known as the powerhouse of the cell, mitochondria are involved in energy production but are not the primary site for tRNA.

3. **Analyzing the Role of tRNA**: Since tRNA is involved in the translation process, which occurs in the cytoplasm, we can conclude that this is where tRNA is predominantly found.

4. **Conclusion**: Based on the analysis, the correct answer is that tRNA is found in the **cytoplasm**.

**Final Answer**: Cytoplasm.
