The Sleeping Beauty system utilizes these elements in vertebrates.
Global mutagenesis using these entities was used to determine the minimal genome for the  rst synthetic organism Mycoplasma laboratorium. The most common example of these entities in humans is evolutionarily derived from the 7Â·SÂ·L RNA encoding the signal recognition particle. The Mu bacteriophage relies on these entities to integrate into the host genome. The replicative forms of these entities require the action of a reÂ·solvÂ·ase for separation. Helitrons are examples of these entities that replicate with a rolling-circle mechanism. The Sleeping Beauty system utilizes these elements in vertebrates. Hybrid dysgenesis in Drosophila is a result of the action of one of these entities known as the P element. They can be used for gene insertions and knock-ins. Class I ("one") of these entities use reverse transcriptase for replication and include LINEs and SINEs ("lines and sines"). For 10 points, Barbara McClintock used corn to discover what DNA sequences that can change positions within a genome?
