The correct Answer is:
**Step-by-Step Solution:** 1. **Understanding the Question**: The question asks for the name of the technique used to separate DNA fragments. 2. **Context of DNA Separation**: DNA fragments are separated for various purposes, such as analyzing genetic material, cloning, or forensic analysis. The separation is necessary after the DNA has been cut into fragments. 3. **Cutting DNA**: DNA is cut into specific fragments using enzymes known as restriction endonucleases. These enzymes recognize specific sequences in the DNA and cleave it at those sites. 4. **Separation Technique**: Once the DNA is cut into fragments, they need to be separated for analysis. The technique used for this separation is called **gel electrophoresis**. 5. **How Gel Electrophoresis Works**: - A gel, typically made of agarose, is prepared and placed in a chamber. - The DNA fragments are loaded into wells in the gel. - When an electric current is applied, the negatively charged DNA fragments move towards the positive electrode. - The movement of the fragments through the gel matrix separates them based on size; smaller fragments move faster and travel further than larger ones. 6. **Visualization**: After electrophoresis, the gel is often stained with a dye (like ethidium bromide) to visualize the DNA fragments under UV light. This allows researchers to see the separated bands of DNA. 7. **Final Answer**: The technique used to separate DNA fragments is **gel electrophoresis**. ---
