Since miRNAs mediate repression of translation [34], it is possible that LARK functions with miRNAs to regulate the translation of certain targets, similar to that postulated for other RNA-binding proteins such as the Fragile×Mental Retardation Protein (FMRP, [56], [57]).
In canonical RNaseH, RNA backbone cleavage proceeds via a two-metal ion mechanism [ 29] similar to that postulated for splicing catalysis [ 30].
A woman there asked Mr. Bush about an article in Vanity Fair magazine that postulates a cause for his frequent malapropisms and lapses of grammar: dyslexia.
Within the context of their eusocial colonies, this reproductive machinery is of direct significance to sociogenomic theory that postulates the existence of 'genes for altruism' [ 79, 80].
This observation provides support for the "escape from light" hypothesis that postulated an early adaptive advantage for organisms by shifting cellular processes sensitive to light into the subjective night phase.
The four categories that are postulated for the constructions that block subalternacy are: reciprocals, and centrifugal, centripetal, and tandem constructions.
For example, the presence of two versions of VDAC in Saccharomyces, but not other Saccharomycetales fungi such as Kluyveromyces lactis (Fig. 3), is in agreement with the genome duplication that is postulated for Saccharomyces [ 52].
Moreover, the suggested metabolism in the Zn world, which combines abiogenic photosynthesis with the primitive heterotrophy of the first replicators, is fundamentally different from the (bio chemical mechanisms that were postulated for the two "iron-sulfide" worlds and based upon iron-catalyzed redox reactions (see the accompanying article [ 226] for more details on this point).
The reason for this was that the postulates for the theoretical language also specify factual relations between phenomena that fall under the concepts that are implicitly defined by them.
Recent experimental support has been generated for a model of prebiotic development that postulates a role for Amyloid-Nucleic Acid (ANA -fibers ANA -fibersiest replicasing entheiearliestle of undereplicatinginian entitiesn.
