DOI: http://dx.doi.org/10.7554/eLife.02407.002 Many steps throughout the transcription cycle of RNA polymerase II (Pol II) can be regulated, and modulation of any step has the potential to alter the timing and output of mRNA production.
With the 'Unidrive' system, you can also change the parameters for the rev limit, valve timing, power output, steering assistance, ABS, noise valve, brake balance, ride height, traction and stability controls.
Grush posits emulators process models in the central nervous system that anticipate, retain, and update mock sensorimotor feedback by timing their output proportionally to feedback from an actual process (see Grush forthcoming).
On the other hand, when tracking the timing of output spikes, the oscillator with the third version of the PRC tends to outperform the oscillator with a phase PDF-matching PRC.
Further studies focused on the timing and output of the cell cycle will be necessary to establish which of the aforementioned mechanisms are responsible.
The approach taken by molecular geneticists to understand life-history events like growth, reproductive timing, reproductive output and life-span has mostly been through reverse genetics.
As we will discuss in detail below, microRNAs appear to play distinct roles in clock physiology, and dysregulation of microRNA expression can lead to marked alterations in circadian timing and output.
About 5%to15%5% of genome-wide mRNA expression exhibits a circadian rhythm that is driven by the clock genes and there is a tissue specificity of cycling genes and a tissue specificity of clock controlled gene expression timing and level (output genes i.e., genes involved in the functional output of an organ) [ 27- 30].
The appearance of uncoupled fictive breaths, especially evident in cervical-lumbar-VII recordings, led us to wonder whether what might appear to be deletions at longer time scales (>1 s) were, in fact, only changes in the relative timing of respiratory output such that lumbar or VII activity occurs at a different phase of the respiratory cycle.
A time-lapse video was acquired at a magnification of 20×, exposure time of 2 s for each colour (green and red), time lapse set at 2 s interval for 5 min. For movie conversion, output timing was set at the interval of 200 ms. Appendix S1.
