Which among the following is identified by Western blotting

The procedure to separate and detect DNA fragments, termed Southern blotting. The Nohern and Western blot transfer techniques are used to size and quantitate specific RNA and protein molecules, respectively. A fouh hybridization technique, the Southwestern blot, examines protein-DNA interactions. In this method, proteins are separated by electrophoresis, blotted to a membrane, renatured, and analyzed for an interaction with a paicular sequence by incubation with a specific labeled nucleic acid probe.
