To examine the role of the flanking sequences in XGRAF:GR function, the γ-flanks were mutated to match the sequences that flank the GRE of the Bβ-fibrinogen gene. Sequence motifs are becoming increasingly important in the analysis of gene regulation. How do we define sequence motifs, and why should we use sequence logos instead of consensus sequences to ...In order to use PCR, one must already know the exact sequences which flank (lie on either side of) both ends of a given region of interest in DNA (may be a gene or any sequence). One need not know the DNA sequence in-between. The building-block sequences (nucleotide sequences) of many of the genes and flanking regions of genes of many different ...

However, the tagged gene sequences cannot be obtained simply by regular PCR procedures because the genomic flanking sequences are unknown. So far, several PCR-based methods, such as inverse PCR ( 1 , 2 ), adapter-ligation-mediated PCR ( 3–6 ), and thermal asymmetric interlaced (TAIL)-PCR ( 7 , 8 ), have been developed for …

In this case, part of the Dam or Dcm sequence is generated by the restriction enzyme sequence, followed by the flanking sequence. This situation should also be considered when designing restriction enzyme digests. Eukaryotic MethylationMoreover, the role of flanking sequence in modulating DNA binding specificity of Ubx and Scr homeodomains, in association with the cofactor Exd, is also reported (28). Thus, the Exd-Hox heterodimer offers a reasonable model system to explore the mechanism by which flanking sequences modulate TF binding at the cognate site.The flanking regions tend to be conserved within the species, although sometimes they may also be conserved in higher taxonomic levels.
