Retrotransposon are a class of transposons which operate by DNA being transcribed into RNA then back to DNA again, via the action of reverse trnascriptase[1]. They are also known as 'jumping genes' as DNA is moved to a different position on the chromosome each time retrotransposition occurs[2].

There are 2 types of retrotransposons[3]:

  1. Long Terminal Receptors (LTRs) - these have structures similar to retroviruses
  2. Non-Long Terminal Receptors (non LTRs) - these are further divided into Long Interspersed Nuclear Elements (LINEs) and Short Interspersed Nuclear Elements (SINEs)
