Basically, it is a technique that was developed by Edward Southern to analyze DNA molecules. During the procedure, a restriction enzyme is used to cut a sample of DNA into fragments that are separated using electrophoresis … Southern blot is a method used for detection and quantification of a specific DNA sequence in DNA samples. This method is used in molecular biology. Briefly, purified DNA from a biological sample (such as blood or tissue) is digested with restriction enzymes, and the resulting DNA fragments are separated by using an electric current to move them through a sieve-like gel or matrix, which allows smaller fragments to move faster than larger fragments. The DNA fragments are transfer… mahindra roxor air filter
