Vedclass · Answer

(D) Gel electrophoresis is a technique used to separate $DNA$ fragments based on their size. $DNA$ molecules are negatively charged due to the phosphate groups in their sugar-phosphate backbone. When an electric field is applied,the $DNA$ fragments move towards the positive electrode (anode). Therefore,the samples are loaded into the wells located at the negative electrode (cathode) end so that they can migrate through the gel matrix towards the positive end.
