The mechainsm by which a gene is able to express itself in the phenotype of an organism is called

Options

A. Gene expression
B. RNA synthesis
C. Translocation
D. Formylation

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks for the mechanism by which a gene expresses itself in the phenotype of an organism. This requires understanding the concepts of genetics and molecular biology.

2. **Identifying the Options**: The options given are:
- Gene expression
- RNA synthesis
- Translocation
- Formylation

3. **Analyzing Each Option**:
- **Gene Expression**: This is the process by which information from a gene is used to synthesize a functional gene product, typically proteins, which ultimately influence the phenotype of an organism. This is a key mechanism in genetics.
- **RNA Synthesis**: This refers specifically to the process of synthesizing RNA from a DNA template. While RNA synthesis is a part of gene expression, it does not encompass the entire mechanism of how a gene influences phenotype.
- **Translocation**: This is a genetic event where a segment of a chromosome is moved to a different location, either within the same chromosome or to another chromosome. This does not directly relate to how a gene expresses itself in the phenotype.
- **Formylation**: This is a chemical modification process that involves adding a formyl group to a compound. It is not related to gene expression or phenotype.

4. **Conclusion**: Based on the analysis, the correct answer is **Gene Expression**. This is the mechanism that explains how genes influence the traits and characteristics (phenotype) of an organism.

**Final Answer**: The mechanism by which a gene is able to express itself in the phenotype of an organism is called **Gene Expression**.
