Why do DNA fragments move towards the anode during gel electrophoresis ?

Explanation

**Step-by-Step Solution:**

1. **Understanding Gel Electrophoresis:**
- Gel electrophoresis is a technique used to separate DNA fragments based on their size. It involves the use of a semi-solid medium, typically agarose gel, which allows the movement of DNA fragments when an electric current is applied.

2. **Electric Current and Charge Movement:**
- In electrophoresis, charged particles move in response to an electric field. Charged particles will move towards the electrode with the opposite charge. This means that negatively charged particles will move towards the positive electrode (anode), while positively charged particles will move towards the negative electrode (cathode).
