What is the criterion for DNA fragments movement on agarose gel during gel electrophoresis?
Option 1 : Positively charged fragments move to farther end.
Option 2 : Negatively charged fragments do not move.
Option 3 : The smaller the fragment size, the farther it moves.
Option 4 : The larger the fragment size, the farther it moves.
