The given diagram shows the separation of DNA fragments of different sizes by using gel electrophoresis method.The DNA fragment that is largest in size is labelled as:
Correct answer: A. Option A
- A. Option A
- B. Option B
- C. Option C
- D. Option D
Explanation
The size of a DNA molecule is inversely proportional to the distance it has traveled during electrophoresis. Option A is the correct answer because this band represents the largest DNA fragment, which has moved the least distance in the gel. It is also closer to the negative pole or end.B and C have travelled moderate distances, whereas D has travelled the greatest distance of all, making these options incorrect.
