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.
Acorn Worms Pterobranchs Phylum Hemichordata Hemichordata is a small, unusual phylum of worm-like creatures closely related to the phylums Chordata and Echinodermata. They vary widely in size, from the 8 ft (2.5 m) lengths of the acorn worms to the 1/25 in (1 mm) lengths of the pterobranchs.irst off, all hemichordates have a 3-fold division of the body, with the preoral lobe, the collar, and the trunk. All hemichordates have pharyngeal slits, or gill slits, that open into the pharynx. Acorn worms have up to 200 of these; pterobranchs have only 1.
