Question

Quizplus · Accepted Answer

Southern blots are used to analyze DNA that has been fractionated based on length. After the DNA has been separated by gel electrophoresis, the fragments are transferred to a membrane (usually nitrocellulose or nylon) and then hybridized with a labeled probe to detect specific DNA sequences. This technique can be used for a variety of applications, such as detecting mutations, identifying genetic markers, and analyzing gene expression.
