Southern blotting is used to detect specific DNA sequences, while northern blotting is used to detect specific RNA sequences. Southern blotting involves DNA samples being digested with restriction enzymes, separated by gel electrophoresis, and then transferred to a membrane for probing. Northern blotting involves RNA samples being separated by gel electrophoresis, transferred to a membrane, and then probed with a complementary RNA or DNA sequence.
