Gel Electrophoresis

Q.

What is the criterion for DNA fragments movement on agarose gel during gel electrophoresis?

1. The larger the fragment size, the farther it moves

2. The smaller the fragment size, the farther it moves

3. Positively charged fragments move farther end

4. Negatively charged fragments do not move
