Pictures Considered #58: Visualizing Introns

by Christoph
By reading sequences we easily detect stretches that code for pro­teins. We detect promoters, transcription factor binding motifs, start/stop signals for tran­scription, signals where introns are removed by splicing from primary transcripts (pre‑mRNA) to yield mature messenger RNA (mRNA), and much more. It wasn't always so easy.

"Transposable elements drive intron gain in diverse eukaryotes" #PNAS #introns #transposons

"...Introners evolved convergently from many distinct genetic elements, most are consistent with DNA-based transposable elements, and they are disproportionately common in the genomes of aquatic organisms. We propose that horizontal transfer of transposons in aquatic taxa contributes to the biased and highly punctate evolution of intron gains across eukaryotes."
