Which of the following statements about gel electrophoresis is correct?a. Longer DNA fragments migrate farther than shorter fragmentsb. Migration distance is inversely proportional to the fragment sizec. Positively charged DNA migrates more rapidly than negatively charged DNAd. None of these statements are true

Gel electrophoresis is a method utilized to separate mixture of DNA, RNA and proteins based on their sizes and charges.

It is based on the principle that most of the fragments are electrically charged and when subjected to an electric field will move on the gel of specific pore size.

The correct answer is:

Option B. Migration distance is inversely proportional to the fragment size of the molecule.

The explanation for this is:

Therefore, the size and shape of the molecule affect the rate of migration.

Migration distance is inversely proportional to the fragment size.

The gel electrophoresis is the process of separation of the DNA fragments after the action of restriction endonuclease action on enzyme. The gel electrophoresis is carried out after coating the DNA fragments with suitable salts and placing them on the side of the electrophoresis table.

The electrophoresis is carried through agar agar gel which has a network inside it.  The smaller DNA fragments will pass more through the gel whereas the larger fragments will be left behind.
