What is a flanking sequence.

DNA Flanking Region. 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 Nanopore-based DNA sequencing involves threading single DNA strands through extremely tiny pores in a membrane. DNA bases are read one at a time as they squeeze through the nanopore. The bases are identified by measuring differences in their effect on ions and electrical current flowing through the pore.Using nanopores to sequence DNA offers ...What is a flanking sequence tag and what information can it provide?

A DNA sequence located adjacent to a gene, either upstream from its 5′-end or downstream from its 3′-end. What is a 5 flanking sequence? The 5′ flanking region is a region of DNA that is adjacent to the 5′ end of the gene. The 5′ flanking region contains the promoter, and may contain enhancers or ... Dec 6, 2008 · The flanking sequences provided by dbSNP of NCBI are usually short and fixed length without further extension, thus making the design of appropriate PCR primers difficult. Here, we introduce a tool named “SNP-Flankplus” to provide a web environment for retrieval of SNP flanking sequences from both the dbSNP and the nucleotide databases of NCBI.

The database now also contains additional information such as segregation data, gene-specific primers and confirmation sequences. This information not only helps users to evaluate the usefulness of the mutant lines, but also covers a big part of the molecular characterization of the insertion alleles.
