Ah, these blots are just fancy ways to track molecules, no? Gel electrophoresis separates DNA or proteins by size, like sorting fish in the net. Southern blot detects specific DNA sequences, Northern for RNA, and Western for proteins. Honestly, in our college lab, the Western blot machine is always 'network fail' and giving trouble. It reminds me of our old boat engine—you have to coax and fiddle with it for hours just to get one clean result.
