The DNA visible under ultraviolet light after gel electrophoresis because : 356038.
The DNA is visible under ultraviolet light after gel electrophoresis because the gel contains a fluorescent salt called ethidium bromide (which is a powerful mutagen and should NOT be allowed to touch your skin). This salt wedges (intercalates) between two helices along the length of the DNA strand. Based on this explanation, which pieces of DNA should be most visible on the gel? which should be least visible?
