Investigations on the reactivity of the feasible catalytic intermediates revealed that the electrophilic P2Pt NCC6F5 22+ initiator is unreactive to XeF2, suggesting that only after cyclization to a monocationic P2Pt alkyl+ complex, is the catalyst sufficiently electron rich to trigger the F+ oxidation/reductive elimination sequence (Scheme 8).
It seems therefore an attractive hypothesis that the assembly and folding state of the platform and the head domain, mirrored by the actual conformation of the platform-head interface, is crucial to trigger the removal of 3' extended spacer rRNA sequences and eventual associated factors.
RNAi describes a mechanism of post-transcriptional gene silencing where dsRNAs trigger the sequence-specific degradation of mRNA [1].
The fusion planning agent is to trigger a sequence of algorithms in the algorithm-pool and discover their required data attributes are in datasets in the data-pool.
These devices are deployed to trigger elaborate action sequences of the kind we get in so many other films today, but didn't get in the Star Trek TV shows, whose low-budget simplicity nurtured, instead, thoughtfulness and imagination.
This method uses the Gal4-upstream activating site controlled hairpins to trigger sequence-specific mRNA breakdown.
When an accident does occur, its cause is usually an error made by the anesthesiologist, either in triggering the accident sequence, or failing to take timely corrective measures.
Daedelus designed some of the procedural elements that trigger the music sequences.
It was the Guardian Edinburgh International Television Festival at the end of August that triggered the fateful sequence of events.
The implication is that the presence of conspecific competitors alone is enough to trigger intruders to modify the behavioural sequence required to parasitise a host.
a, The mutations observed to trigger this process generate DNA sequences (red star) that lead to the production of messenger RNA molecules for which translation is prematurely terminated.
