 Transposable element

A genetic element capable of moving or producing copies that insert at new positions in a genome. Repression of its expression can prevent mobilization before insertional damage occurs.

Transposable elements (TEs), often referred to as "jumping genes," are DNA sequences that can change their position within the genome of a single cell. This ability to move or "transpose" can lead to various effects on the organism, including gene regulation, genetic diversity, and evolution.
