The process of 'Southern blotting' is a technique used in molecular biology to detect: MCQ with Answer and Explanation

Southern blotting, named after its inventor Edwin Southern, is a laboratory method used to detect specific DNA sequences in a complex DNA sample. The process involves digesting DNA with restriction enzymes, separating the fragments by gel electrophoresis, transferring (blotting) them onto a nylon or nitrocellulose membrane, and then hybridizing the membrane with a labeled, complementary DNA or RNA probe. Northern blotting detects RNA, and Western blotting detects proteins.
