Transposons are segments of DNA that can move within a genome, potentially causing mutations or changes in genome size. They may play a role in evolution by transferring genetic material and increasing genetic variability. Transposons and their host genomes have co-evolved, and transposon activity can increase in response to the environment. Transposons contain regulatory genes that control their own activity and may evolve to control other genes as well.

1. Transposons are the segments of DNA that can move around to different positions in the genome
of a single cell which may cause mutations or increase/decrease the amount of DNA in the
genome of the cell. Theycan potentially play an important role in evolution by copying and
transferring other genetic material. There is evidence that transposons and their host genomes
have co-evolved over long periods and that transposon activity may increase in response to
environmental factors. The movement of transposons is a source that increases genetic
variability. In particular, transposons contain regulatory genes that control transposon activity. It
is thought that these regulatory genes may evolve to control other genes as well.
