If a DNA fragment is cut by a restriction enzyme resulting in two fragments of 1.5 kb and 2.5 kb, and these are separated by agarose gel electrophoresis, which fragment will travel further towards the anode?
A
1.5 kb fragment
B
2.5 kb fragment
C
Both fragments travel equally
D
None of the fragments travel
Correct Answer
