Answer:
B. The smaller DNA pieces travel farthest towards the positive end of the box
Explanation:
Gel-electrophoresis technique is a technique which is used to separate the fragments of DNA based on their size. The technique is employed in the DNA fingerprint analysis.
The DNA samples are loaded on one side of the gel and when an electric current is applied, the DNA moves from the wells towards the electrodes.
The DNA is a negatively charged molecule which travels through pores in the gel and reaches towards the electrode with positive charge.
The smaller the size of the DNA fragment, the faster it moves.
Thus, Option-B is correct.
