NEET Zoology Recombinant DNA MCQ Question
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?
1.5 kb fragment
2.5 kb fragment
Both fragments travel equally
None of the fragments travel
Correct Answer
Detailed Explanation
Smaller DNA fragments travel further during agarose gel electrophoresis due to the sieving effect of the gel, as mentioned in the NCERT context. Therefore, the 1.5 kb fragment will travel further than the 2.5 kb fragment.
