This model is commonly termed ‘‘looping,’’ as it requires that the intervening DNA be looped out or otherwise organized in order to permit the enhancer-promoter interaction (Bulger and Groudine, 1999; Blackwood and Kadonaga, 1998; de Laat et al., 2008).
Sample text:```Unlabeled DNA substrates containing consensus 12-RSS, 23-RSS, Hox11 or non-specific DNA sequences (DAR81/82) were prepared from oligonucleotides described previously [11,24].```
Sample intent: background
Sample text:```Quantitative geneticists have documented numerous cases of such interactions (Stuber et al. 1992; Ragot et al. 1995; Cockerham and Zeng 1996; Melchinger et al. 1998).```

Sample text:```This study supports the theory of a tumor origin from multipotential progenitor cells.(14) Reports of the Ki67 labeling index have demonstrated great variety.```

Sample text:```This discovery, along with the fact that both intrinsic and Rho-dependent terminators have associated pausing, suggested that antipausing can underlie antitermination, which is at least partly true (126).```

Sample text:```We screened for potential TF binding sites using STAMP [59], with the motifs’ position weight matrices (PWMs) retrieved from the TRANSFAC database [60].```

Sample text:```This process is controlled not only by the protein-coding segments of the genome but also by non-coding regions, including loci that produce small RNAs (Grivna et al., 2006; He et al., 2009; Thomson and Lin, 2009).```

Sample text:```Because previous studies indicated that hexapeptides bind the junction core (29, 32), we tested two junctions, one with an AT-rich core and the other with a GC-rich core (Fig.```

Sample text:```Instead of using the single fuzzless locus mutant developed mapping populations (Rong et al. 2005, 2007; Zhang et al. 2005; Guo et al. 2006; Wan et al. 2007), the common female parent line of the two F2 populations we developed combined at least two fuzzless loci (N1 and n2, and probably n3) (Turley and Kloth 2002).```

Sample text:```This is interesting in relation to the result from our previous CGH study (comparing the number of significantly hybridizing probes on the microarray) that showed high sequence divergence on the Z chromosome between the common whitethroat and the zebra finch [62]; and such patterns are also found in other species [48,51,69].```
