Examples

  • The authors also reported that the mouse Rps23r1 gene, whose human counterpart has not yet been identified, was created during evolution through a process called retroposition, in which a gene is "duplicated" through the reverse transcription of mRNA and the "duplicate" is placed in a different location in the cell's DNA.

  • The team also found that the Rps23r1 gene, whose human counterpart has not yet been identified, was created through a process called retroposition, in which a gene is duplicated through the reverse transcription (or reading) of mRNA and the duplicate is placed in a different location in the cell's DNA.

  • By duplication, amplification, recombination, retroposition, and similar mechanisms, nuons can give rise to “potonuons,” that is, entities potentially recruitable as new nuons.

  • They include exon shuffling, gene duplication, retroposition, transposable elements, lateral gene transfer, gene fusion/fission and coding regions arising de novo from non-coding regions.

  • For example, when a retroposition occurs, it is the result of reverse transcription, not some arbitrary, accidental happenstance.
