Sequences of DNA can be removed from a genome with the help of

Options

A. Molecular glue
B. Molecular scissors
C. Ligases
D. Nucleases

Answer

To solve the question "Sequences of DNA can be removed from a genome with the help of," we need to analyze the options provided and understand the concept of DNA manipulation.

### Step-by-Step Solution:

1. **Understanding the Question**: The question asks about the method or tool used to remove DNA sequences from a genome.

2. **Analyzing the Options**:
- **A. Molecular Glue**: This term generally refers to substances that can bind DNA together, not remove it.
- **B. Molecular Scissors**: This refers to enzymes that can cut DNA at specific sites. These are known as restriction endonucleases or restriction enzymes.
- **C. Ligases**: These are enzymes that join DNA fragments together, not remove them.
- **D. Nucleases**: While nucleases can degrade nucleic acids, they are a broader category and not specifically known as "scissors."

3. **Identifying the Correct Tool**: The term "molecular scissors" is commonly used to describe restriction enzymes. These enzymes cut DNA at specific sequences, allowing for the removal of DNA segments.

4. **Conclusion**: Based on the analysis, the correct answer is **B. Molecular Scissors**.

### Final Answer:
**B. Molecular Scissors**
