Name and explain the technique that helps in the separation of DNA fragments for DNA recombinant technology experimants. How can these separated DNA fragments be visualised ?

Explanation

### Step-by-Step Solution:

1. **Identify the Technique**: The technique used for the separation of DNA fragments in recombinant DNA technology is called **Agarose Gel Electrophoresis**.

2. **Explain the Principle**: Agarose gel electrophoresis separates DNA fragments based on their size and charge. Since DNA is negatively charged due to its phosphate backbone, it will migrate towards the positive electrode (anode) when an electric current is applied.

3. **Prepare the Gel**: Agarose gel is prepared by dissolving agarose powder in a buffer solution and allowing it to solidify in a mold. The concentration of agarose can vary, which affects the pore size of the gel.
