Answer:
DNA is negatively charged. When an electrical current is passed through a gel, the DNA is repelled by the nearby negative current and pushed across the gel towards the positively charged side.
Explanation:
Electrophoresis has become a standard molecular biology technique. This technique is based on the use of a constant-uniform electric field that enables the separation and identification of DNA fragments with different lengths, which form bands in the electrophoresis gel. Electrophoresis can be used to analyze not only DNA, but also RNA and proteins. During electrophoresis, the fragments of DNA that are negatively charged will migrate towards the positively charged electrode, where the duration of this movement will depend on the size of the DNA fragment, as well as of the pore size in the gel.
