  • So the thing which you think is most unlikely, the sudden incorporation of the transposon from a bacterium, right into the right spot in the right receptor in some early fish genome, didn't have to happen all in one step, indeed we now have evidence that it did not.

    Assessing Applegate's Attack

  • At these positions, although the trigger works fine, and the transposon is silenced, once the trigger is lost, the transposon reawakens, said Jaswinder Singh, a professor in the Plant Sciences Department at McGill University, and lead author of the new article.

    Can't We All Be Friends?

  • It has been proposed that in transposon-containing regions of the genome both DNA strands are transcribed, dsRNA is formed, and the RNAi process eliminates these undesirable products.
