Why are flanking sequences important.
The effect of the flanking sequences is dependent on the identity of the base pair at position 8. So far, we have studied two different core TATA boxes, in which the modulation of binding stability by the flanking sequences is significant, (T-A) 4 and T 5 T 7 (Table 1). Do same flanking sequences influence these two TATA boxes similarly?
Molecular characterization of sequence flanking exogenous fragment insertion is essential for safety assessment and labeling of genetically modified organism (GMO).

Flanking regions of the gene are often found to be of importance in determining the pattern and level of expression of the gene. The best understood flanking regions are the promoter where transcription starts and regions further away from the start of the gene (this is known as the 5′–end whereas the end of the gene is 3′) which interact ... Long-Terminal Repeats (LTR) LTR is present on either side of the viral genome. It harbors cis -acting elements, which are required for RNA synthesis, and is the initiation site for transcription of the viral genome. LTR consists of three regions: U3 (unique, 3′ end), R (repeated), and U5 (unique, 5′ end).
