Maximum amount of RNA is found in

Options

A. Cytoplasm
B. Nucleous
C. Ribosomes
D. Chlorophasts.

Answer

To determine where the maximum amount of RNA is found, we can analyze the options provided: cytoplasm, nucleolus, ribosomes, and chloroplasts.

### Step-by-Step Solution:

1. **Understanding RNA Types**:
- RNA (Ribonucleic Acid) is crucial for various biological functions and exists in three main forms:
- **mRNA (messenger RNA)**: about 5% of total RNA.
- **rRNA (ribosomal RNA)**: about 80% of total RNA.
- **tRNA (transfer RNA)**: about 15% of total RNA.

2. **Analyzing Each Option**:
- **Cytoplasm**:
- Contains some RNA, but it is not the location with the highest concentration of RNA.
- **Nucleolus**:
- This is a region within the nucleus where rRNA is synthesized, but it does not contain the maximum amount of RNA compared to other structures.
- **Ribosomes**:
- Ribosomes are primarily composed of rRNA, which constitutes about 80% of the total RNA in a cell. Therefore, ribosomes are likely to have the highest concentration of RNA.
- **Chloroplast**:
- Chloroplasts do contain RNA, but again, they do not have the maximum amount compared to ribosomes.

3. **Conclusion**:
- After evaluating all the options, it is clear that ribosomes, which are rich in rRNA, contain the maximum amount of RNA in the cell.

### Final Answer:
The maximum amount of RNA is found in **ribosomes**.
