<prompt> Which among the following is identified by Western blottingDNARNAProteinst-RNA  <response>: 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.
