Transposable Element

— filed under:

A transposable element (=TE) is a small stretch of DNA that can move from one location in the genome to another.

There are many different types of TEs that fall in two broad categories:

  • DNA transposons (move directly)
  • Retrotransposons (make a  copy that is inserted elsewhere).

TEs can have many different structures. Their strategies for choosing where they insert can also vary widely from random to specific target sequences.
