NEET Zoology Genetic Engineering MCQ Question

Type: MCQ-numerical-Medium-Class 12

If a DNA fragment is cut using a restriction endonuclease and results in fragments of sizes 500 bp, 1500 bp, and 2000 bp, how would these fragments separate on an agarose gel during electrophoresis?

A

500 bp fragment moves furthest towards the anode.

B

2000 bp fragment moves furthest towards the anode.

C

All fragments move equally towards the anode.

D

1500 bp fragment moves furthest towards the anode.

Correct Answer

Option A

Detailed Explanation

DNA fragments separate based on size during gel electrophoresis, with smaller fragments moving faster and thus further. Hence, the 500 bp fragment moves furthest.
