Final answer:
Southern blotting is a technique used to detect specific DNA sequences in a given DNA sample by separating DNA fragments, transferring them to a nylon membrane, and incubating them with a complementary DNA probe.
Step-by-step explanation:
Southern blotting is a molecular technique used to detect the presence of specific DNA sequences in a given DNA sample. It involves separating DNA fragments using gel electrophoresis, transferring them to a nylon membrane, and then incubating them with a DNA probe that is complementary to the sequence of interest.
This technique helps researchers identify and isolate DNA fragments of interest.
