MHT CET · BIOLOGY · STD 12 - 4. Molecular Basis of Inheritance
Agarose gel electrophoresis is used to separate DNA fragments. The DNA fragments separate due to _________ .
- A difference in their staining property
- B difference in the base sequence in them
- C positive charge on the fragments
- D difference in the size of fragments
Answer & Solution
Correct Answer
(D) difference in the size of fragments
Step-by-step Solution
Detailed explanation
The DNA samples are loaded on agarose gel for electrophoresis under an electric influence. The DNA fragments, which are negatively charged move to the positive pole. The movement of these fragments depends on the length of the fragments.
