The TATA box is present in all genes that are transcribed by RNA polymerase II, which is most eukaryotic genes. CAAT box. The CAAT box is a ...The standard polymerase chain reaction (PCR) is used to amplify a segment of DNA that lies between two inward-pointing primers. In contrast, inverse PCR (also known as inverted or inside-out PCR) is used to amplify DNA sequences that flank one end of a known DNA sequence and for which no primers are available.

The origin of microsatellite flanking sequence similarity remains unknown (Meglécz et al. 2007 ) but has been hypothesized to result from association of minisatellites and mobile DNA elements ...

For all the sequences, the ribozyme regions (from 1 to 73) all fold to the same structure during transcription. However, the existence of the 30-nt upstream flanking sequence can inhibit the ribozyme region folding into the active native state through forming an alternative helix Alt1 with the segments 70–90.The sequence reads corresponding to boundaries of inserted T-DNA, and associated native flanking sequences were identified by bioinformatic comparison with the soybean reference genome (Wm82.a2.v1) and the transformation vector sequence.

Flanking UTR sequences affect LANA1 and EBNA1 G4s differently. The GAr-Ova and the Ova-GAr reporter constructs showed that the localisation of the G4-containing translational inhibitory sequence within the coding sequence is important for some, but not all, G4-related activities. We next wanted to know if changes in the non-coding sequences can ...

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. The mutated upstream flank, mutU*, lies near the XGRAF binding site and the mutated downstream flank, mutD, borders the GR binding site.

A region of DNA which is NOT copied into the mature mRNA, but which is present adjacent to 3′ end of the gene . The 3′ Flanking region often contains sequences which affect the formation of the 3′ end of the Message. …. It may also contain enhancers or other sites to which Proteins may bind.DNA interacting enzymes recognize their target sequences embedded in variable flanking sequence context. The influence of flanking sequences on enzymatic activities of DNA methyltransferases (DNMTs) can be systematically studied with “deep enzymology” approaches using pools of double-stranded DNA substrates, which contain target sites in random flanking sequence context.the sequence. They are surrounded by nonvariable segments of DNA known as flanking regions. For example, the STR allele in Figure 1 could be designated as “6” because the repeat unit (GATA) repeats six times, or as 70 bp (where bp stands for base pairs) because it is 70 bp in length, including the flanking regions.

Briefly, for each gap, we first identified two BAC sequences flanking the gap locus that were aligned concordantly (identity > 99.9%) to both the ONT-HiC assembly and a HiFi contig, and then replaced the gap-containing contigs with corresponding HiFi contigs. We used the same method to polish ONT-HiC assemblies with HiFi contigs.Starting from a limited amount of known sequence to identifying the sequences flanking it, is a challenge relevant to many analyses (Table 1). One common application is the identification of viral and mobile element (transposons, retrotransposons) integration sites across a host genome, which is central to understanding integration preferences ...

Insertion sequence. Insertion element (also known as an IS, an insertion sequence element, or an IS element) is a short DNA sequence that acts as a simple transposable element. Insertion sequences have two major characteristics: they are small relative to other transposable elements (generally around 700 to 2500 bp in length) and only code for ...The flanking sequences provided by dbSNP of NCBI are usually short and fixed length without further extension, thus making the design of appropriate PCR primers difficult.
