By using restriction enzymes specific for sites flanking the VNTR, fragments of variable lengths in different individuals can be obtained because each subject has a different number of repeats. Fragments can also be obtained and multiplied by PCR using primers complementary to the VNTR flanking sequences.

Meslet-Cladière and Vallon (2012) determined the flanking sequences of 38 randomly selected insertion mutants in a transposon insertion mutation library of the model organism C. reinhardtii. These authors used the 3′ end of the RACE technique. Twenty-seven (71%) were valid flanking sequences, and 23 could be accurately localized in the genome.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.

Proteins with more than 400 residues were selected for further analyses.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 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.The optimal distance between the two nicks was 40–68 nt for Cas9 D10A, and 51–68 nt for Cas9 H840A.

The term ‘flanking region’ usually refers to regions of the genome up to 103–104 bases on either side of the terminal exons of a gene, and which especially contain promoter and other regulatory sequences [99,100]. From: Cancer Letters, 2004. Related terms: DNA; Allele; Exon; Intron; Nested Gene; RNA; Genetic Code; Mouse Here, we examine two flanking sequences bordering a site in the γ-fibrinogen gene regulatory region that binds a heterodimer of the Xenopus glucocorticoid receptor accessory factor (XGRAF) and the glucocorticoid receptor (GR). Mutation of the upstream flank results in a decrease in XGRAF binding, but little change in hormone induction.CRISPR/Cas13a (formerly C2c2) from the bacterium Leptotrichia shahii is an RNA-guided CRISPR system that targets sequences in RNA rather than DNA. PAM is not relevant for an RNA-targeting CRISPR, although a guanine flanking the target negatively affects efficacy, and has been designated a "protospacer flanking site" (PFS). GUIDE-SeqThe observed upstream sequence motif and the patterns of sequence conservation flanking the stem–loop portion of the miRNA genes motivated us to develop an improved miRNA gene-finding algorithm, which we call MiRscanII.

region of the sequence that was comprised of the same set of nucleotides repeated over and over again. When he later found another region of repeats within a different globin gene, he was inspired to look throughout the genome and found dozens more. Today, more than 1000 are known. VNTRs were the first

This promoter has internal control sequences. Deletion of 5' flanking DNA still permits efficient transcription of (most) genes transcribed by RNA PolIII. Even the intial part of the gene is expendable, as is the 3' end. Sequences internal to the gene (e.g. +55 to +80 in 5S rRNA genes) are required for efficient initiation, in contrast to the ...

The utility of sequence capture technology to recover nonprobe sequences representing the DNA flanking the targeted regions of interest was first demonstrated in maize (Zea mays L.)(Fu et al., 2010) and subsequently in identification of novel retrotransposition events in the human genome (Baillie et al., 2011).The sequence contains the upstream flank, the STR sequence, and the downstream flank in forward direction, or as reverse complimentary if the strand was specified as reverse in the configuration file.

This may be useful for PCR primer determination. Masked Sequence File. The masked sequence file is a FASTA format file containing a copy of the sequence with every character that occurred in a tandem repeat changed to the letter N. The word "masked" is added to the sequence …input sequences carrying major and minor allele respectively. For example, for DNase peak, if the likelihood generated from sequence with major allele is much higher than that from sequence with minor allele, it suggests a potential loss of DNase peak in minor allele carriers. DeepSEA is a pre-trained deep genome annotation model built on the
