Figure 2.
Hexanucleotide content of R- and P-regions. For the R-segment sequence (A) and the P-segment sequence (B), the plots show the relative frequencies (vertical axes) of each possible hexanucleotide. Hexanucleotide sequences are arranged in the horizontal plane, with the homopolymers (T)6, (A)6, (C)6, and (G)6 at the corners of the plane as indicated. The sequences of the most abundant hexamers in the R-segment sequence (all circular permutations of CAGCAG or its complement) are indicated in A; the peak labeled “Tel” and others of similar height are hexamers from the telomere-like motif AGGGTTT, its complement, and circular permutations thereof.
