Retrotransposons are a type of transposable element, or transposon The Alu sequence
Added by Eric A.
Step 1
Retrotransposons are a type of transposable element that can replicate and insert themselves into new locations in the genome through an RNA intermediate. They are classified into two main classes: LTR (long terminal repeat) retrotransposons and non-LTR Show more…

Worksheet 14 – Mobile Genetic Elements: Transposons and Retroviruses 1. For the following question, refer to Figure 9-26 in the book (shown above) to help answer the different scenarios. Mobile genetic elements can move exons from one gene to another. What consequences might occur should the mobile genetic elements land: -Here is a link to a video to help you visualize how these elements move around the genome: https://www.youtube.com/watch?v=N_NQ5KVtLcA a) In a protein gene's exon b) In a protein gene's intron c) In a regulatory region of a gene d) In an intergenic DNA with no known function.

How does a retrotransposon move?
One similarity between DNA transposons and retrotransposons is that transposition results in movement of the original transposon to a different place in the genome. both can encode an enzyme required for mobilization. they both have poly-A segments at one end. during transposition, both go through an RNA form that is copied back into DNA.
