The Charlesworth-Langley hypothesis is associated with their location, and the Shapiro intermediate is associated with these objects that often encode the enzyme resolvase. University of Minnesota researcher Perry Hackett used an inactive salmon gene to make an artificial and hyperactive example of one of these that is known as Sleeping Beauty. Their existence was hinted at by the C-value paradox, and they were first identified when working on Dissociation and Activator mutations. Prominent examples include P elements, which are found in Drosophila, Alu sequences, which are found in humans, and members of the Tc1/Mariner family, which operate by a cut-and-paste mechanism. For 10 points, name these genetic elements that were discovered by Barbara McClintock and are able to jump to other sites within the genome.
