In this sense, PU.1 is considered to have a 'pioneer' role in establishing competence for genes to be regulated, in a positive or negative fashion, depending on the cross-talk with other transcription factors and co-factors.
Minichromosome maintenance (Mcm) proteins 2 7, the core components of the DNA replication initiation machinery, participate in the assembly of pre-replicative complexes (pre-RCs) on chromatin in G1 phase of the cell cycle, establishing competence for initiation of DNA synthesis in the subsequent S phase (Machida et al, 2005; Remus and Diffley, 2009).
Minichromosome maintenance proteins (Mcm2 7) participate in the assembly of prereplicative complexes to establish competence for initiation of DNA synthesis (DNA replication licensing).
It will also review assessment methodologies for establishing competence including traditional techniques, novel automatic assessment based on simulator-derived performance data, and observer-based methods.
Summative assessments are used to establish competence or qualification for advancement.
Factors that favour utilizing a similar organization structure include scope for donor trust, for bringing in established competence and a comprehensive approach.
If she can draw a line under Rudd's errors, get a grip and establish competence quickly, Julia Gillard is likely to get Labor back on track for re-election.
This could be due to the Pbx-Hox input establishing a competence for the enhancer to drive expression within particular rhombomeres, which is further restricted to specific sub-domains within the rhombomeres by the influence of other regulatory inputs to the enhancer.
Because the number of FL-L1s capable of reverse transcription remains unclear, it is perplexing whether the subset of reverse-transcribed FL-L1s is large enough to establish transcriptional competence for a large cohort of genes.
A captive xenodiagnosis study (65) of gray squirrels would be the most suitable approach to establish their reservoir competence for different B. burgdorferi sensu lato genospecies, with measurement of infection rates in engorged larvae that are allowed to molt into nymphs.
In the first step, during the G1 phase key replication initiation factors, including the origin recognition complex, the Cdc6 protein and the MCM proteins 2 7 are recruited into PRCs at future replication origins, establishing the competence of particular chromatin regions for initiation of DNA synthesis (Tye, 1999; Labib and Diffley, 2001; Lei and Tye, 2001; Yu et al, 2004b).
