In summary, levels of molecular divergence within the P. chusua s.l. group are sufficient to suggest that several species are present, but the molecular groupings do not correspond well with species circumscriptions based on morphology; a detailed and comprehensive revision, integrating molecular, morphological and ecological data, is clearly needed.
Although scientists have great understanding of individual molecules, the limitations of modern technology have restricted the study of molecular groupings, or "machines," within cells.
In order to test whether the differentiation in shell morphology is congruent with the molecular genetic groupings, morphometric landmark analyses were conducted with the group of Orcula species endemic to the Alps and the Alpine-Dinarid O. conica.
In our analysis, gene sets were created from different functional groupings, molecular classifications, tissues, and other microarray screens [35].
In our analysis, gene sets were created from different functional groupings, molecular classifications, tissues, and other microarray screens.
However, molecular-based sub-grouping according to gene expression profile is impractical in laboratories equipped for routine diagnostic tests, and provides an imprecise picture of the actual sub-classes [ 27] because mRNA levels do not always correspond to changes in protein expression [ 9].
The groups that are most different for each of the three sets of groupings, biological process, molecular function and cellular process are highlighted in the figures.
Atomic characteristics (number of nitrogen atoms and number of non-aromatic conjugated Cp2 carbon atoms, in the case of the AFP model) have a direct relationship to functional groupings and hence molecular action, whilst electronegativity, (in the case of the MLP model) is a determinant in reactivity and thus has a direct bearing on mechanistic factors.
Previously described subspecies provide convenient (although not necessarily biologically meaningful) labels for most terminal haplogroups, however in six instances the molecular data support non-taxonomic groupings; namely in Angola, the Middle Zambezi Valley, the Luangwa Valley, Upper Volta, Lower Volta and Niger (Table S2).
The groupings based on molecular phylogeny did not correspond with the extant familial classification; Galeommatidae and Lasaeidae were found to be polyphyletic.
Within the Molecular Function ontology nine major groupings were found including phospholipid-hydroperoxide glutathione peroxidase activity, ethanolamine kinase activity, translation activator activity, ISG15 ligase activity, GTPase activity, protein disulfide isomerase activity, fatty acid transporter activity, protein binding, and NAD binding.
