Why do some dna fragments move farther than others during gel electrophoresis ?

The DNA fragments having shorter size than other move faster than other. Explanation: Gel electroscopes is a technique used to separate DNA fragments according to their size. DNA samples are loaded into wells  at one end of a gel, and an electric current is applied to pull them through the gel. DNA fragments are negatively charged, so they move towards the positive electrode. Hence short fragments having less number of nuecleotides move faster than long fragmentas.

Because their masses are different

D because their masses are different Explanation: they undergo a push by the electric field the heavier strand moves the least and the lightest moves the most

Gel electrophoresis is a technique used to separate DNA fragments according to their size. … DNA fragments are negatively charged, so they move towards the positive electrode. Because all DNA fragments have the same amount of charge per mass, small fragments move through the gel faster than large ones. Explanation:
