What is a flanking sequence.
In this study, the sequence similarity calculation was based on the BLOSUM62 matrix; the neighborhood was set to 0.25, 0.5, 1, 2, and 4% of the training dataset, respectively; and the flanking sequence size was set to 13 amino acids (±6 at each side). Disorder score is a feature to measure the stability of the local structure.
In this way, flanking residues were combined in order to match or exceed the μ-values calculated for the WT protein. Flanking residues that matched the WT protein sequence and a limited number of permutations of the various flanking sequences were also studied. (Table S2 provides the full list of μ-values for the peptides in this study.)Inverse PCR DNA involves digestion by a restriction enzyme of a preparation of DNA containing the known sequence and its flanking region. The individual restriction fragments (many thousands in the case of total mammalian genomic DNA) are converted into circles by intramolecular ligation, and the circularized DNA is then used as a template in PCR.Here we describe the sequence of the 5' flanking region, cod- ing sequence and 3' untranslated region of the canine FVIII gene. In combination with a well ...Protospacer flanking sequence (PFS) for Cas13 mediated RNA targeting. ( A ) Schematic representation for gRNAs targeting SS regions with PFS (nucleotide in green background) in the RNA structure.
In genetics, floxing refers to the sandwiching of a DNA sequence (which is then said to be floxed) between two lox P sites. The terms are constructed upon the phrase "flanking/flanked by LoxP". Recombination between LoxP sites is catalysed by Cre recombinase. Floxing a gene allows it to be deleted (knocked out), translocated or inverted in a ...In genetics, floxing refers to the sandwiching of a DNA sequence (which is then said to be floxed) between two lox P sites.

Floxing a gene allows it to be deleted (knocked out), translocated or inverted in a ...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.
Simple sequence repeats (SSR) – also known as microsatellites – have been used extensively in genetic analysis, fine mapping, quantitative trait locus (QTL) mapping, as well as marker-assisted selection (MAS) breeding and other techniques. Despite a plethora of studies reporting that perfect SSRs with stable motifs and flanking sequences are more efficient for genetic research, the lack of ...

A fragment of the IHJ is also shown with the LTR in lower case. (f) An example of alignment between a FLEA-PCR-derived flanking sequence (Query) with a human genome database sequence (Sbjct).
The lack of 100-bp sequences eliminated possible overrepresentation of MITEs in close proximity to the genes. The results were very similar to those obtained for the full-size flanking sequences consisting of gene-coding sequences, introns, and full-size spacers (Table 2 and SI Appendix, Table S3). Thus, although MITEs are overrepresented in ...
The flanking DNA sequences and 57 water molecules at the enzyme-DNA interface were removed from the model. The starting crystallographic R-factor was 31.1%, and this was reduced to 19.6% by several rounds of model building iterated with positional B-factor and simulated annealing refinement in XPLOR (27).Protospacer flanking sequence (PFS) for Cas13 mediated RNA targeting.

T1 weighted (T1W) sequences are part of almost all MRI protocols and are best thought of as the most 'anatomical' of images (historically the T1W sequence was known as the anatomical sequence), resulting in images that most closely approximate the appearances of tissues macroscopically, although even this is a gross …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.
