Question

The technique used for separating DNA fragments is

• A. Southern blotting
• B. ELISA test
• C. Western blot test
• D. All of the above

Answer 1

Answer: (A)

Southern blotting

Southern blotting is a technique that is used for separating and identifying specific DNA fragment. In this, the DNA sequence of interest is separated on a gel are transferred directly to a second medium on which hybridization is carried out to identify the desired DNA sequence. Enzyme-linked immunosorbent assay (ELISA) is used to detect antibodies or infectious agents. Western blot test is a technique that is used for identifying the specific protein.

Thus, the correct answer is option A.
