Gel electrophoresis

Vedclass · Answer

(B) Gel electrophoresis is a laboratory technique used to separate mixtures of $DNA$,$RNA$,or proteins according to molecular size. In this process,the molecules are pushed by an electrical field through a gel that contains small pores. $DNA$ fragments are negatively charged,so they move towards the positive electrode (anode). Smaller fragments move faster through the gel matrix than larger ones,allowing for their separation based on size.

$P$. Restriction endonuclease	$I$. Synthesizes $DNA$ copies
$Q$. $DNA$ polymerase	$II$. Cleaves $DNA$ molecules
$R$. $DNA$ ligase	$III$. Joins $DNA$ molecules

Which technique is used to separate $DNA$ fragments?
