The molecules, called chitinases, were long considered a primordial response to certain parasites and insects.
The last P-cell, P4, has no somatic descendants and, at least by lineage analysis, is restricted to germ cell fate and thus is often considered a primordial germ cell (PGC).
In the context of a UV-irradiated environment such confinement could be considered a rescue since an eventual detachment of a primordial polymer from the energy-absorbing ZnS surface would have led to faster photodestruction.
Archetype, (from Greek archetypos, "original pattern"), in literary criticism, a primordial image, character, or pattern of circumstances that recurs throughout literature and thought consistently enough to be considered a universal concept or situation.
(Clearly, he didn't pay much attention to the ending, in which Robin and his band withdraw to a primordial commune unless it can be considered an armed compound).
Sesn1 is considered the primordial member of the family and most similar to invertebrate Sesns (Lee et al, 2010).
In particular, we consider a modification to that proposal designed to account for breaking the symmetries of the initial quantum state, leading to the generation of the primordial inhomogeneities.
Simultaneous with PLLV formation, LECs located more closely to the CV aggregate to form a large lumenized structure, which can be considered as the primordial TD (pTD).
PreSET, SET, and PostSET are considered to be primordial domains [ 29], and they are usually organized in proteins in the order PreSET/SET/PostSET, as seen in the Suv subfamily.
These chlorophyllic tips could be considered as shoot primordial in the form of protocorm - like body (PLB) formation which originated from the surface of callus and were often slightly translucent.
The minerals considered as potential primordial templates (see ref. [ 10] for their survey) are characterized by meshes of positively charged metal ions, so that a prospective oligomer unit required a negatively charged template-binding group (phosphate was the natural choice [ 10]) and a spacer region needed to fit into the lattice of positively charges at the template.
