What are flanking sequences.

The bases or nucleotides adjacent to the repeats are referred to as flanking sequences. An individual can have two versions, or alleles, of an STR sequence, one from each parent—for example, one allele with 9 CTA units and one with five CTA units. There may be many different alleles among individuals in a population, with each allele having a ...The optimal distance between the two nicks was 40–68 nt for Cas9 D10A, and 51–68 nt for Cas9 H840A.

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.Protein legacy names are given in parentheses. PAM stands for protospacer adjacent motif, PFS stands for protospacer flanking site, and 3’ flank stands for 3’ flanking sequence of the protospacer that is non-complementary to the 5’-tag of crRNA; each of which are used for self vs. non-self recognition. Nucleic acids are not to scale with ...The blue colour shows the RNA sequences derived from the RE element, and the green marks the last 16 nt at the sequenced RNA 3′ ends, which align with the transposon flanking DNA.

Short hairpin RNA (shRNA) sequences are usually encoded in a DNA vector that can be introduced into cells via plasmid transfection or viral transduction. shRNA molecules can be divided into two main categories based on their designs: simple stem-loop and microRNA-adapted shRNA. A simple stem-loop shRNA is often transcribed under the control of ...The second class represents flanking sequences identical only to expressed sequence tag sequences without matches to genome sequences. The third class of gene disruptions has been identified solely by homology of the translated flanking sequences with proteins in GenBank. Sequencing data represent the status of the database as of April 2, 1999.

Analysis of sequences flanking T-DNA. Positions of the T-DNA insertions were deduced from the results of homology alignment of each FST against the TIGR assembly of rice chromosomes 1–12 (sequence accessions AP008207 to AP008218) using the blast N program. The vector sequence was masked prior to this homology search.
