Sequences of DNA used in the AFM experiments. (a) Schematic representation of the PPC (2885) and sequence of the region analyzed (953 bp) that contains the hyperperiodic fragment Ω4 from C.elegans (923 bp). In the PPC the hyperperiodic region is located at both ends of the molecule, hence tracing of the molecule is independent of the particular end chosen as a starting point. Capital case letters denote the hyperperiodic fragment Ω4 from C.elegans. (b) Sequence of SQ100 fragment (185 bp, non-periodic) that contains the fragment Ω7 and (c) sequence of SQ322 (182 bp, hyperperiodic) that contains the fragment Ω6 from C.elegans. Two or more consecutive As or Ts were colored in green and red, respectively. The sequences were plotted in columns of 10 bases to highlight ∼10 bp periodicities. Capital letters in (a) denote the hyperperiodic fragment Ω4 from C.elegans and in (b and c) denote the Ω7 and Ω6 fragments, respectively.
