Question

Which technique is used in separating fragments of DNA ______________.

• A. Eastern blotting
• B. Western blotting
• C. Northern blotting
• D. Southern blotting

Answer 1

The correct option is D Southern blotting

Southern blotting is a laboratory technique used to detect a specific DNA sequence in a blood or tissue sample. A restriction enzyme is used to cut a sample of DNA into fragments that are separated using gel electrophoresis. The DNA fragments are transferred out of the gel to the surface of a membrane.

So the correct answer is option D.
