Nettet29. sep. 2016 · The closed plasmid comes in three different forms: nicked-relaxed, supercoiled and circular single-stranded. All three forms have a different tertiary structure and thus they run differently on the gel.

The linear form is seen as a minor component in the nicked sample, and its starting position is less than 0.5 mm further downfield compared to that of the circular forms. sarh lucy charlesworth
