Examination of the phylogenetic distribution of these lysozymes reveals that c-type lysozymes are predominantly present in the phylum of the chordata and in different classes of the arthropoda moreover, g-type lysozymes (or at least their corresponding genes) are found in members of the chordata, as well as in some bivalve mollusks belonging . A subphylum of the phylum chordata vertebrates have all chordate features at some time in their lives they also have marked development of the brain, which is enclosed in a skull a skeleton of cartilage or bone a spinal column that partially or completely replaces the notochord and a closed, relatively high-pressure cardiovascular system.

Nucleotide skew in the t4 genome t4 dna has only 345% g+c, while its e coli host has about 50% g+c if t4 were assembled from “modules” of other genomes, as has been suggested for many phages (discussed below), different regions might be expected to have quite different g+c contents, particularly if they were recently acquired.

The life cycle of u maydis differs greatly from the mushroom life cycle in its details, but it shares the heterokaryotic phase with other members of the phylum (figure 110) the smut alternates between a budding yeast phase and a filamentous mycelium the yeast phase is saprotrophic and can be cultured in the lab, but the mycelium grows only . Orders may be combined into classes, and classes into phyla (sing phylum) or divisions in the case of metaphyta for example, the brachiopods comprise some 11 orders split between two classes and these two classes are the major subdivisions of the phylum brachiopoda . For each time bin, the number of phyla that were present during the beginning of the interval were tallied (ie, metazoan diversity) so, for example, 3 of the 11 phyla originated before the beginning of the ediacaran, whereas an additional 3 phylum-level crown groups had appeared by the beginning of the cambrian.
