The smaller $DNA$ fragments separate first.

Vedclass · Answer

(D) The correct answer is $D$. The statement 'The smaller $DNA$ fragments separate first' is technically incorrect in the context of the final separation pattern,as they migrate the fastest and reach the farthest point,but they do not 'separate first' in a chronological sense; rather,they are the ones that travel the furthest distance through the gel matrix.Gel electrophoresis is a technique that uses an electric field to separate $DNA$ molecules based on their size.Since $DNA$ molecules are negatively charged due to the phosphate backbone,they migrate towards the positive electrode (anode).The rate of migration is inversely proportional to the size of the $DNA$ fragment.Smaller $DNA$ fragments encounter less resistance from the agarose matrix and thus migrate faster and travel further than larger fragments.Therefore,the band located farthest from the loading well represents the smallest $DNA$ fragment.
