Flanking sequence definition.

Short Tandem Repeats. Short tandem repeats (STRs), or “microsatellites,” are tracks of tandemly repeated short (1 to 6 bp) DNA sequence motifs. STRs may occur in both intergenic and intragenic regions, including within genes, and account for approximately 3% of the human genome. Some microsatellites are highly mutable and show both sequence ... Nov 28, 2017 · The UniVec sequence matching the query segment includes the cloning site or adjacent sequence of a vector. Even short matches to a multiple cloning site (MCS), or to the sequence flanking a cloning site of a vector, are strong evidence that the segment has a foreign origin. Inteins are naturally occurring intervening sequences that catalyze a protein splicing reaction resulting in intein excision and concatenation of the flanking polypeptides (exteins) with a native peptide bond. Inteins display a diversity of catalytic mechanisms within a highly conserved fold that is shared with hedgehog autoprocessing proteins.Sequences flanking the irg copies and definition of ISNgo2 and ISNgo3. (A) The relative order and orientation of the irg genes are shown with flanking genes; gaps are indicated by // .

Assigning single cell long reads to 10x 3’ cellular barcodes (when barcodes are unknown) Flexiplex can be run in two passes: 1) to find the barcode sequences and 2) assign them to reads. To find barcodes, set the flanking edit distance to 0 (a perfect match) as these are less likely to have errors in the barcodes.
