DNA transposons

DNA transposons, also known as "jumping genes," are segments of DNA that can move from one location to another within the genome. They function like natural genetic elements capable of excising themselves from one site and inserting into a new one. This process is mediated by enzymes called transposases, which recognize specific sequences and catalyze the movement. DNA transposons play a role in genetic diversity and evolution but can also cause mutations if they insert into or disrupt important genes. Their ability to move within the genome makes them significant in shaping genetic variation across generations.
