Southern blotting
Southern blotting is a laboratory technique used to detect specific DNA sequences in a sample. The process starts by cutting DNA into smaller pieces, which are then separated by size using gel electrophoresis. The separated DNA is transferred onto a membrane and treated with a labeled probe, a short piece of DNA that binds to the target sequence. After washing away unbound probe, scientists can visualize the specific DNA they are interested in. This method is useful in genetics, for identifying mutations, and in forensic science, among other applications.

Southern blotting is a laboratory technique used to detect specific DNA sequences within a sample. It involves extracting DNA from cells, cutting it into smaller pieces with enzymes, and then separating these pieces by size using a gel. The DNA is then transferred onto a membrane and treated with a labeled probe, which binds to the target sequence of interest. After washing away unbound probes, the location of the specific DNA sequence can be visualized, allowing researchers to study genetic information and identify variations related to diseases or other traits.
