NEET Zoology Recombinant DNA MCQ Question
During gel electrophoresis, DNA fragments are separated based on their size. If a DNA fragment of 500 base pairs (bp) and another of 1000 bp are subjected to electrophoresis on an agarose gel, which fragment will migrate further towards the anode?
500 bp
1000 bp
Both migrate equally
Neither will migrate
Correct Answer
Detailed Explanation
According to the NCERT text, DNA fragments separate based on size, with smaller fragments migrating further during gel electrophoresis. Therefore, the 500 bp fragment will migrate further than the 1000 bp fragment.
