DNA fragments of 100 base pairs (bp), 300 bp and 500 bp were separated by agarose gel electrophoresis. Pick the correct arrangement of the fragments separated on the gel in the increasing order of their migration from the wells.
1
500 bp < 300 bp < 100 bp
2
100 bp < 300 bp < 500 bp
3
100 bp > 300 bp > 500 bp
4
500 bp > 300 bp > 100 bp
