Vedclass · Answer

(D) The separation of $DNA$ fragments based on their size is achieved through a technique called $Gel$ $electrophoresis$.In this process,$DNA$ fragments are separated by forcing them to move through a gel matrix (usually agarose) under an electric field.Since $DNA$ molecules are negatively charged,they move towards the anode (positive electrode).The smaller fragments move faster and travel further through the pores of the gel compared to larger fragments,allowing for effective separation.

Separation of $DNA$ fragments is done by a technique known as:
