Question

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:

पर्याय

• Both statement I and statement II are correct.

• Both statement I and statement II are incorrect.

• Statement I is correct but statement II is incorrect.

• Statement I is incorrect but statement II is correct.

Answer 1

Both statement I and statement II are correct.

Explanation:

Recombinant DNA can be created by extracting DNA fragments separated by gel electrophoresis. DNA travels toward the positive end of the electrode (anode) in agarose gel electrophoresis because it is negatively charged. Larger fragments remain close to wells, but smaller fragments move more quickly and farther away.
