, Mobile Genetic Elements & Role in Evolution
• ‘’Are jumping genes’’
• A DNA sequence able to insert itself (or a copy of itself) a
new location in the genome without having any sequence
relationship with the target locus.
• Transposition: movement of transposons from one site to
another in the same or different DNA.
• Found in almost all organisms
• Mainly knowns as transposable elements
