Flank sequence.
The digest was run on a TBE acrylamide gel and analyzed by fluorescent imaging. The double stranded oligos were designed to have the indicated number of base pairs from the end followed by the recognition sequence and an additional 12 bases. In some cases asymmetric cleavage was observed and interpreted as a negative result.
Unlike the binding of RAG1 plus RAG2, RAG1 can bind to DNA in the absence of a divalent metal ion and does not require the presence of coding flank sequence. Footprinting of the RAG1-RAG2 complex with 1, 10-phenanthroline-copper and dimethyl sulfate protection reveal that both the heptamer and the nonamer are involved. (Refer to picture) Suppose you know the sequence of a region of DNA in an organism, but you want to know the unknown sequences that flank the known sequence.

Schematic of RSS with consensus sequence for heptamer and nonamer elements. The spacer, found between the nonamer and heptamer, has low sequence conservation but is either 12 or 23 bps in length. Sequence adjacent to the heptamer at the site of RAG cleavage is termed the coding flank.
We also enumerated the number of low complexity sequences in the dataset (a sequence was defined to be low complexity if a particular nucleotide is repeated in 50% of sequence positions). <2% of the flank sequences were identified as low complexity (as opposed to <1% of peak sequences) indicating that flank sequences are not enriched for low ...

Jul 12, 2023 · T-DNA sequence flank lengths. The length of the flanks varied when using either CLC Bio or Geneious software for the same genotype. Geneious provided on average longer flanks (Supplementary Table 2). The average flank length at the left end T-DNA was 344 bp in CLC Bio and 567 bp in Geneious. Codon composition is known to influence translation efficiency. Translation efficiency, mRNA abundance, and protein folding may all be affected by codon optimization. Although high GC-content may cause problems for mRNA secondary structure, the higher GC sequence translates 100-fold higher than a low GC sequence (Kudla et al. 2006).3' flanking region. A region of DNA which is NOT copied into the mature m RNA, but which is present adjacent to 3' end of the gene .
