The P. falciparum 3D7 nuclear genome is composed of 22.8 megabases (Mb) distributed among 14 chromosomes ranging in size from approximately 0.643 to 3.29 Mb (Fig. 1, and Supplementary Figs AâN). Thus the P. falciparum genome is almost twice the size of the genome of the fission yeast Schizosaccharomyces pombe.
