To avoid DNA amplification during RT-qPCR, it is advisable to select primers that either flank a large intron that is not present in the mRNA sequence or that span an exon-exon junction (Figure 6.2). Intron/exon annotations for known genes from many vertebrate, bacteria, protist, fungi, plant and invertebrate metazoan species are available at ... Here, we examine two flanking sequences bordering a site in the γ-fibrinogen gene regulatory region that binds a heterodimer of the Xenopus glucocorticoid receptor accessory factor (XGRAF) and the glucocorticoid receptor (GR). Mutation of the upstream flank results in a decrease in XGRAF binding, but little change in hormone induction.DNA Flanking Region Natural Product Biosynthesis by Microorganisms and Plants, Part B.

The position and orientation of the primers in a PCR reaction allow copy numbers to build up exponentially. The innovation with PCR is in having two primers flanking the target sequence. If you were to set up a reaction with one primer, you could make one DNA copy at a time. But with two primers, copy numbers grow exponentially with each cycle.

Just as eukaryotic circular RNA (circRNA) is a product of intracellular backsplicing, custom circRNA can be synthesized in vitro using a transcription template in which transposed halves of a split group I intron flank the sequence of the RNA to be circularized. Such permuted intron-exon (PIE) constructs have been used to produce ... The 5′ flanking region is rich in G+C and contains a GGGCG and a TATATAA sequence 76 and 160 bases upstream from the transcription initiation site, respectively. The sequence CAACGG is located 85 and 146 bases upstream from this site, representing a presumptive binding site for the Myb transcription factor.This sequence percent correctness may be used in place of a confidence score. The reciprocal flank alignment start position also determines the stop position of the gap itself. We can thus use the start of GapPredict’s prediction and the start of reciprocal flank alignments to extract gap sequences predicted by GapPredict.
