Gel electrophoresis

Vedclass · Answer

(C) Gel electrophoresis is a laboratory technique used to separate $DNA$ fragments based on their size and charge. In this process,$DNA$ samples are loaded into wells of an agarose gel and an electric current is applied. Since $DNA$ molecules are negatively charged,they migrate towards the positive electrode (anode). The smaller fragments move faster through the pores of the gel matrix compared to larger fragments,resulting in their separation.

Which technique is used for the separation of $DNA$ fragments?
