Sentence examples for origin of classes from inspiring English sources

This suggests that a functional change occurred after the duplication at the origin of classes III and I/II.

This coincided exactly with the origin of class IA regulatory proteins.

Absence of class II regulatory subunits and the recent origin of class I regulatory subunits is puzzling given that the class I/II catalytic subunit was present in LECA and has been conserved in most present-day eukaryotic lineages.

Both studies identified an ancient gene duplication event that lead to the separation of class III and I/II catalytic subunits that was followed by a more recent duplication at the origin of class I and II.

While we favour this interpretation, we note that cryptic ancient losses can never be ruled out (and are not inconceivable given the RNR gene mobility documented here), and an early origin of class I is in fact plausible under the 'respiration early' hypothesis [ 50- 52], and given plausibility of abiotic oxygen generation in the early oceans [ 53].

The original creators of UML point out the influence of ER models on the origins of class diagrams.

The structural and sequence alignments in Additional file 1: Figure S11, while supporting the common origin of all classes of GPCRs from MRs and revealing the conservation of the key Trp residue in the glutamate receptors, support the suggestion that the ancestors of class C GPCRs evolved independently from other GPCR classes [ 10, 19, 32, 33].

In the phylogenetic tree of the class VIII myosins, the algae homologs form a group separating at the origin of the class followed by the fern (Selaginella moellendorfii; Sem) and moss (Physcomitrella patens; Php) myosins.
