Vedclass · Answer

(A) $DNA$ molecules contain a sugar-phosphate backbone where the phosphate groups carry a negative charge.Due to this negative charge,$DNA$ fragments migrate towards the positively charged electrode,which is the anode,when an electric field is applied during gel electrophoresis.Therefore,both the Assertion and the Reason are correct,and the Reason is the correct explanation for the Assertion.

$A$ : During gel electrophoresis,the $DNA$ fragments move towards the anode.
$R$ : $DNA$ fragments are negatively charged molecules.
