What is the Southern blotting method of DNA analysis? Who developed it?
What will be an ideal response?
A transfer method developed by Edward Southern, called Southern blotting, is used. In this process, the DNA is transferred to a nylon membrane in much the same way that ink is transferred to a blotter. The nylon sheet is then treated with radioactively labeled DNA probes, single-stranded pieces of DNA that can bind through complementary base pairing with target DNA. Whereas a single-locus probe “looks” for only one field, a multilocus probe looks for numerous fields simultaneously. The radioactive probe then merges with the specific DNA sequences found on the membrane fragments. The images that result from X-ray film placed in contact with the membrane to detect the probe configuration look like the price bar codes used on supermarket products.
