Transposable elements (TEs), popularly called “jumping genes” are sequences of DNA that can move around to different chromosomal positions in a cell.
First TEs were discovered in maize in 1948 by Barbara McClintock
Awarded the Nobel Prize in 1983
Why transposable elements?
(1902-1992)
TEs make up a large fraction of genome sizes in most higher organisms:
TEs were often referred to be “molecular junk”, but are now recognized as important, even crucial parts of the blueprints of plants and animals:
~50% ~35%
