Explanation

DNA transposition is the process, which involves the movement of DNA elements from one site in the genome to the other. It is mediated by transposase enzymes. These short segments of DNA (DNA elements) with remarkable capacity to move from one location in a chromosome to another, are called transposons or jumping genes or transposable elements or mobile genetic elements. These were first discovered by Barbara McClintock in maize (Zea mays) for which she got the Nobel Prize for physiology and medicine.
