The difference disappears when the RNA transcript harbored by the enzyme is digested with RNase A, suggesting that GC-rich RNAs form stronger secondary structures that prevent pausing, most likely by limiting backtracking.
Again, Sen1 assisted fork progression across these regions, preventing pausing, although we did not detect massive accumulation of aberrant structures as in the case of the highly expressed PDC1 locus.
Taking some string and measuring approximately how much cable you need between each device can prevent an awkward pause when you go to pick out your cables and see five different length options and their alternatives.
It differs from Medtronic's MVP algorithm in that it incorporates a programmable maximum AV delay up to 450 ms to prevent the potential marked pauses that have been reported with the MVP algorithm.
Natural pauses lead to a stuttering that occurred on average every 152.3 s, which was rare enough in order to prevent confusion with song pausing elicited by a sequence of ultrasound pulses (see example in Fig. 2B).
In fact, Chase And Status had more cause for concern, the dance outfit pausing to prevent crushing at the front.
But as Google has grown, and the company sees the threat of others on the horizon, it seems that "do the right thing" may have been paused to prevent itself from fading like a Yahoo or an AOL.
Mrs. Ishido, accidental foreign policy informant that you are, your instruction for us to take a pause and prevent a chain reaction of hate, is prophetic and healing.
The Metal A and Metal B sites bind magnesium ions that guide free nucleoside triphosphates into the active site for RNA synthesis, stabilize the transition state of the growing RNA chain and participate in transcript cleavage events during polymerase backtracking, a process which helps prevent polymerase arrest at pause sites [17], [18].
However, it has been shown that NELF-mediated Pol II pausing can prevent the encroachment of nucleosomes at the promoter-proximal region, suggesting that NELF may support multiple rounds of transcription in vivo by maintaining a nucleosome-free region at the promoter (Gilchrist et al., 2010; Sun and Li, 2010).
