Figure 3.

C. parvum chromosome 6. The chromosome is shown in two halves (heavy vertical lines). Start points of predicted coding sequences on the + and - strands of the chromosome are indicated by short green horizontal lines to the left and right, respectively (red: tRNA genes). Octamer palindrome motifs are indicated by short black (TGCATGCA) and red (TGGCGCCA) bars, respectively, polymorphisms by blue bars. Two gaps in the sequence are indicated, and the STS markers mapped within them are shown in expanded form (upper left). The A+T content (sliding window of 100 bp) of a representative 50-kbp segment of the chromosome is shown in expanded form (graph, lower left), aligned with protein-coding regions on the + (green bars) and - (red bars) strands.
