B) Northern blotting
C) Southern blotting
D) Eastern blotting

Question

Quizplus · Accepted Answer

Western blotting is the procedure used to identify a specific protein within a mixture of many different protein molecules. In this technique, proteins are separated by size using gel electrophoresis and then transferred onto a membrane (blotted). The membrane is then probed with a specific antibody that recognizes the target protein, allowing identification and visualization of the protein of interest. Northern blotting is used to detect specific RNA molecules, Southern blotting is used to detect specific DNA molecules, and Eastern blotting is not a commonly used technique for protein identification.
