Can you help me with this question?

1) Transposable elements, "jumping genes", were first described
by Barbara McClintock in her Nobel prize winning studies
with corn. The genome of every multicellular eukaryote that
has been sequenced is composed of a large percentage of
transposable elements (often 30% to 50%), but they are nearly
absent from the genomes of eubacteria and archea.
What are these things and what do they do?
• Describe and draw the structural organization and
mechanism for movement of transposons and
retrotransposable elements.
• What effect do these elements have on the stability of
genomes?
