Ribosomes contain large quantities of

Options

A. haemoglobin
B. fatty acids
C. ribonucleic acid
D. doxyribonucleic acid

Answer

### Step-by-Step Solution

1. **Understanding Ribosomes**: Ribosomes are cellular structures responsible for protein synthesis. They can be found either free-floating in the cytoplasm or attached to the endoplasmic reticulum.

2. **Composition of Ribosomes**: Ribosomes are made up of two main components: ribonucleic acid (RNA) and proteins. The RNA component is crucial for their function in synthesizing proteins.

3. **Types of RNA in Ribosomes**: The ribosomal RNA (rRNA) is a key component of ribosomes. Additionally, transfer RNA (tRNA) and messenger RNA (mRNA) play significant roles in the protein synthesis process.

4. **Function of Ribosomes**: Ribosomes read the sequence of the mRNA and translate it into a polypeptide chain (protein) by linking together the appropriate amino acids, which are brought to the ribosome by tRNA.

5. **Conclusion**: Given the composition and function of ribosomes, it is clear that they contain large quantities of ribonucleic acid (RNA).

### Final Answer
Ribosomes contain large quantities of **ribonucleic acid (RNA)**.
