Southern blotting is a hybridization technique for identification of particular size of DNA from the mixture of other similar molecules. Macromolecule Blotting and Probing The terms northern, western and eastern blotting are derived from what initially was a molecular biology joke that played on the term Southern blotting, after the technique described by Edwin Southern for the hybridisation of blotted DNA. Although with the advancement of molecular biology techniques, most bioscience researchers still heavily rely on the western blot technique for protein analysis. The discipline particularly seeks to understand the molecular basis of genetic processes; molecular biologists map the location of genes on specific chromosomes, associate these genes with particular characters of an organism, and use genetic engineering (recombinant DNA technology) to isolate, sequence, and modify specific genes.
