NEET Zoology Recombinant DNA MCQ Question
If a DNA fragment of 500 base pairs is subjected to gel electrophoresis using agarose gel, which fragment size would move fastest towards the anode?
200 base pairs
500 base pairs
700 base pairs
1000 base pairs
Correct Answer
Detailed Explanation
According to the NCERT context, smaller DNA fragments move faster through the agarose gel due to the sieving effect. Therefore, a fragment of 200 base pairs would move faster than a fragment of 500 base pairs.
