Vedclass · Answer

(D) Agarose gel electrophoresis is a technique used to separate $DNA$ fragments based on their size.When an electric field is applied,the negatively charged $DNA$ fragments move towards the anode (positive pole).The gel matrix acts as a molecular sieve,where smaller fragments move faster and travel further through the pores of the gel compared to larger fragments.Therefore,the separation of $DNA$ fragments is primarily based on the difference in their size.

Agarose gel electrophoresis is used to separate $DNA$ fragments. The $DNA$ fragments separate due to . . . . . . .
