According to the text, which of the following is NOT a recognized way that transposable elements contribute to genome evolution?

  • A: Promoting recombination.
  • B: Disrupting cellular genes or control elements.
  • C: Carrying entire genes or individual exons to new locations.
  • D: Introducing entirely new gene families through horizontal gene transfer.
  • E: Facilitating the formation of new protein domains through exon insertion.

Explanation

The text explicitly states three ways transposable elements contribute to genome evolution: promoting recombination, disrupting cellular genes or control elements, and carrying entire genes or individual exons to new locations. Horizontal gene transfer is a separate mechanism for introducing new genetic material and is not described as a direct contribution of transposable elements in this context.
