Given below are two statements :

Statement I : The DNA fragments extracted from gel electrophoresis can be used in construction of recombinant DNA.

Statement II : Smaller size DNA fragments are observed near anode while larger fragments are found near the wells in an agarose gel.

In the light of the above statements, choose the most appropriate answer from the options given below :

1. Both statement I and statement II are correct

2. Both statement I and statement II are incorrect

3. Statement I is correct but statement II is incorrect

4. Statement I is incorrect but statement II is correct

1 answer

Best answer

Answer: 1. Both statement I and statement II are correct

Key idea: Gel electrophoresis separates DNA by size, and the separated bands can be reused.

  • Statement I is correct. Cut bands are eluted (extracted) from the gel and then ligated into vectors to make recombinant DNA.
  • Statement II is correct. DNA is negatively charged, so it moves towards the anode. Smaller fragments move faster and travel farther, while larger fragments stay near the wells.

Both are correct, so option 1.
