What are flanking sequences
A powerful application of CRISPR/Cas genome editing technology involves the precise insertion or substitution of DNA sequences at specific genomic loci via the homology-directed repair (HDR) pathway.

On the other hand, there is a wide variety of VNTRs and STRs on eukaryotic genomes. Detection of STR or VNTR polymorphism is by PCR using primers that hybridize to nonpolymorphic flanking sequences. The amplification products are then either analyzed by electrophoresis or undergo fragment analysis using a capillary sequencer.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.Four gRNAs were designed flanking the HRE and exon 2, with two gRNAs targeting the 3’ DNA sequence downstream of the HRE and two targeting the upstream, 5’ sequence (Fig. 1a).
Beyond transcripts. Current HGVS recommendations state (see Reference Sequences): “5’ and 3’ flanking sequences are considered to be outside the boundaries of a transcript reference sequence and can not be used to describe variants”.As a consequence, variants removing an entire gene or the 5’ or 3’ end of a transcript can only be described using …Apr 9, 2016 · region of the sequence that was comprised of the same set of nucleotides repeated over and over again.
