$DNA$ fragments separate according to their size.

Vedclass · Answer

(C) Gel electrophoresis is a technique used to separate $DNA$ fragments based on their size.$DNA$ molecules are negatively charged due to the phosphate groups in their backbone,so they move towards the positively charged electrode (anode) when placed in an electric field.The smaller fragments move faster and travel further through the agarose gel matrix compared to larger fragments.Spooling refers to the process of removing purified $DNA$ from a solution using a glass rod,not cutting bands from a gel.$DNA$ fragments are typically stained with ethidium bromide $(EtBr)$ and visualized under $UV$ light,not methylene blue.
