Which of the following is used to select genes of interest from a genomic liberary

Options

A. Cloning vectors
B. DNA probes
C. Gene targets
D. Restriction enzymes

Answer

To solve the question "Which of the following is used to select genes of interest from a genomic library?", we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Question**: The question asks for the method or tool used to select specific genes from a genomic library.

2. **Identify the Options**: The options provided are:
- Cloning vectors
- DNA probes
- Gene targets
- Restriction enzymes

3. **Define Each Option**:
- **Cloning Vectors**: These are tools used to introduce foreign DNA into host cells but do not directly select genes of interest.
- **DNA Probes**: These are single-stranded DNA sequences that can hybridize with complementary sequences in the genomic library to identify specific genes.
- **Gene Targets**: This term generally refers to the specific genes that researchers are interested in but does not refer to a method of selection.
- **Restriction Enzymes**: These are enzymes that cut DNA at specific sequences but do not select genes.

4. **Analyze the Correct Option**: Among the options, DNA probes are specifically designed to detect and bind to complementary sequences in the DNA, making them the correct choice for selecting genes of interest from a genomic library.

5. **Conclude the Answer**: The correct answer to the question is **DNA probes**.

### Final Answer:
The correct option is **DNA probes**.
