(A) Agarose gel electrophoresis is a technique used to separate $DNA$ fragments based on their size.Since $DNA$ molecules are negatively charged due to the phosphate backbone,they move towards the anode $(+)$ when an electric field is applied.The agarose gel acts as a molecular sieve.Smaller $DNA$ fragments move faster through the pores of the gel matrix compared to larger fragments,resulting in their separation based on size.

On what basis are $DNA$ fragments separated in agarose gel electrophoresis?
