Non-genomic RNA takes part in

Options

A. Transfer of hereditary information
B. Protein synthesis
C. Inhibition in operon
D. Induction in operon.

Answer

### Step-by-Step Solution:

1. **Understanding Non-Genomic RNA**:
- Non-genomic RNA refers to RNA molecules that do not serve as genetic material. Instead, they play various roles in cellular processes. The main types of non-genomic RNA include messenger RNA (mRNA), transfer RNA (tRNA), and ribosomal RNA (rRNA).

2. **Identifying Types of RNA**:
- **mRNA (Messenger RNA)**: Carries the genetic information from DNA to the ribosome, where proteins are synthesized.
- **tRNA (Transfer RNA)**: Brings amino acids to the ribosome during protein synthesis, matching the amino acids to the coded mRNA sequence.
- **rRNA (Ribosomal RNA)**: Forms the core of the ribosome's structure and catalyzes protein synthesis.

3. **Analyzing the Options**:
- **Transfer of Hereditary Information**: This is primarily the role of genomic RNA (like DNA in humans), so this option is incorrect for non-genomic RNA.
- **Protein Synthesis**: Non-genomic RNA, specifically mRNA, tRNA, and rRNA, are directly involved in the process of protein synthesis. This option is correct.
- **Inhibition in Operon**: Operons are typically regulated by DNA, although RNA can play a role in regulation, this is not the primary function of non-genomic RNA.
- **Induction in Operon**: Similar to inhibition, induction is more about the regulation of gene expression, which primarily involves DNA. Non-genomic RNA does not directly induce operon activity.

4. **Conclusion**:
- The correct answer to the question "Non-genomic RNA takes part in" is **protein synthesis**.

### Final Answer:
Non-genomic RNA takes part in **protein synthesis**.
