Study the following statements regarding separation of DNA using agarose gel electrophoresis.

1. Large fragments of DNA molecules move faster than small DNA fragments and thus separate faster.
2. DNA being negatively charged migrates to cathode.

पर्याय

• Statement ii is correct while statement i is incorrect.

• Both the statements i and ii are correct.

• Statement i is correct while statement ii is incorrect.

• Both the statements i and ii are incorrect.
