    1. TEs are transposable elements.

      Transposons are mobile DNA elements.Can move throughout the genome. Can be catagorised as class 1 (retrotransposons) or class 2 (DNA transposons).

      Class 1 comprises TEs with LTRs, retroposons (LINE), SINEs.

      Class 2 comprises TEs that operate under replicative transposition or non-replicative transposition. Replicative transposition (nick and paste) -- a total of two TEs as an end result, one as part of the donor and one as part of the target sequence. cointegrate.

      Non-replicative transposition (cut and paste) - only one TE generated, in the target.

      Examples of DNA-only transposon:
