Flanking sequence definition.

In genetics, floxing refers to the sandwiching of a DNA sequence (which is then said to be floxed) between two lox P sites. The terms are constructed upon the phrase "flanking/flanked by LoxP".

The individual restriction fragments (many thousands in the case of total mammalian genomic DNA) are converted into circles by intramolecular ligation, and the circularized DNA is then used as a template in PCR.

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 other protein binding sites. It is the region of DNA that is not transcribed into RNA. Not to be confused with the 5′ untranslated region, this region is not transcribed into RNA or translated into a functional protein.

By analyzing the effects of single base substitutions around the ATG initiator codon in a cloned preproinsulin gene, I have identified ACCATGG as the optimal sequence for initiation by eukaryotic ribosomes. Mutations within that sequence modulate the yield of proinsulin over a 20-fold range. A purine in position -3 (i.e., 3 nucleotides upstream from the ATG codon) has a …

Simple sequence repeats have been found in all eukaryotic species that were scrutinized for them (Tautz and Renz, 1984). To amplify SSRs by PCR, information on unique flanking DNA sequences is required for primer design. The amplification products are size separated by electrophoresis and visualized by silver staining or fluorescent dyes. 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].

Inteins display a diversity of catalytic mechanisms within a highly conserved fold that is shared with hedgehog autoprocessing proteins.

Transposons are segments of DNA that can move around to different positions in the genome of a single cell.
