This is the process by which the biological information contained in the base sequence of DNA is made available to the cell

Options

A. Gene supression
B. Gene regulation
C. Gene expression
D. Gene flow

Answer

To answer the question, "This is the process by which the biological information contained in the base sequence of DNA is made available to the cell," we will analyze each option step by step.

### Step-by-Step Solution:

1. **Understanding the Question**: The question asks for the process that allows the biological information in DNA to be utilized by the cell. This involves the conversion of genetic information into functional products, such as proteins.

2. **Analyzing Option A - Gene Suppression**:
- Gene suppression refers to the process of silencing or inhibiting the expression of a gene. This means that the information in the DNA is not being made available to the cell.
- **Conclusion**: Option A is incorrect.

3. **Analyzing Option B - Gene Regulation**:
- Gene regulation involves the mechanisms that control the expression of genes, determining when and how much of a gene product is produced. While it is related to gene expression, it does not directly refer to the process of making the information available.
- **Conclusion**: Option B is incorrect.

4. **Analyzing Option C - Gene Expression**:
- Gene expression is the process by which the information encoded in the DNA is transcribed into RNA and then translated into proteins. This is the direct mechanism through which the biological information in DNA becomes functional within the cell.
- **Conclusion**: Option C is correct.

5. **Analyzing Option D - Gene Flow**:
- Gene flow refers to the transfer of genetic material between populations, which does not pertain to the process of utilizing DNA information within a single cell.
- **Conclusion**: Option D is incorrect.

### Final Answer:
The correct answer is **Option C: Gene Expression**.
