Flanking sequence definition.

When only limited sequence information is available, for example a 3′-flanking sequence, TAR cloning with vectors that have two specific targeting sequences is impossible.May 15, 2022 · Tufts University & Harvard. Transposons are segments of DNA that can move around to different positions in the genome of a single cell. In the process, they may cause mutations and increase (or decrease) the amount of DNA in the genome of the cell, and if the cell is the precursor of a gamete, in the genomes of any descendants.
