Agarose extracted from sea weeds finds use in

Options

A. Tissue culture
B. PCR
C. Gel electrophoresis
D. Spectrophotometry

Answer

**Step-by-Step Solution:**

1. **Understanding Agarose**: Begin by recognizing that agarose is a natural polysaccharide derived from seaweeds. This is important because it sets the context for its applications.

2. **Identifying Applications**: Next, we need to consider the various options provided in the question: tissue culture, PCR, gel electrophoresis, and spectrophotometry.

3. **Analyzing Each Option**:
- **Tissue Culture**: This involves growing cells in a controlled environment, which does not typically require agarose.
- **PCR (Polymerase Chain Reaction)**: This technique amplifies DNA but does not directly use agarose.
- **Gel Electrophoresis**: This is a method used to separate DNA fragments based on size, and agarose is commonly used to create the gel for this process.
- **Spectrophotometry**: This technique measures the amount of light absorbed by a sample, and agarose is not used in this process.

4. **Conclusion**: After analyzing the options, it is clear that the most relevant application of agarose extracted from seaweeds is in gel electrophoresis, specifically in the preparation of agarose gels for separating DNA fragments.

5. **Final Answer**: Therefore, the correct answer to the question is **gel electrophoresis**.
