Figure 3

Schematic view of N. ovalis macronuclear chromosome structure and the purine/pyrimidine ratios. Lengths of the various parts composing the chromosome and cDNA are displayed. The combination of short leaders, short introns and single genes leads to very short chromosomes. In this figure we can observe as well that the purine/pyrimidine skew is higher than 0 in the coding strand, allowing the prediction of coding strands for chromosomes without a homolog among known proteins.
