A dot plot can be used to check if a DNA sequence contains a subsequence of which the reverse complement also exists or not. How does the conceptual plot look like for such a sequence S? (Note that Sis placed horizontally 5' to 3! S, the reverse complement of S, is place vertically 5' to 3!) For example, S = nnnnnACTTGnnnCAAGTnnn is such a sequence, as ACTTG's reverse complement is CAAGT. (Note that an n is a nucleotide and is irrelevant.) S S' S S' S S' S S
