the sequence. They are surrounded by nonvariable segments of DNA known as flanking regions. For example, the STR allele in Figure 1 could be designated as “6” because the repeat unit (GATA) repeats six times, or as 70 bp (where bp stands for base pairs) because it is 70 bp in length, including the flanking regions. A

Thus, the Exd-Hox heterodimer offers a reasonable model system to explore the mechanism by which flanking sequences modulate TF binding at the cognate site.

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 ...

Although seemingly simple, this process is relatively new and quite complex. In most cases, gene targeting with the use of floxing is enhanced and catalyzed through a process known as Cre/lox recombination. We would like to show you a description here but the site won’t allow us. The flank is the fleshy part of the body between the ribs and hips.
