Jumping library
open-in-new
<p>Jumping libraries or junction-fragment libraries are collections of <a href="/facts/Genome/tjhWET4V">genomic</a> <a href="/facts/DNA/nB89Iauz">DNA</a> fragments generated by <a href="/facts/Chromosome_jumping/XrhyPkne">chromosome jumping</a>. These libraries allow the analysis of large areas of the genome and overcome distance limitations in common cloning techniques. A jumping library clone is composed of two stretches of DNA that are usually located many kilobases away from each other. The stretch of DNA located between these two "ends" is deleted by a series of biochemical manipulations carried out at the start of this cloning technique. </p>
