Українська: Figure 4. The comparison of RNA processing of the cox1 transcript in representative euglenozoans. In contrast to Trypanoplasma borreli and Diplonema papillatum, the cytochrome c oxidase subunit 1 (cox1) transcript of Euglena gracilis (in green) does not undergo RNA editing, splicing, or polyadenylation prior to its translation. In Trypanoplasma, cox1 undergoes RNA editing in the form of numerous uridine insertions (small blue “u”) and deletions (blue star), followed by polyadenylation (in red). The Diplonema cox1 transcript is formed by trans-splicing of nine small fragments called modules M1 thru M9 (in green), which is accompanied by the insertion of six uridines between the modules M4 and M5. Finally, the transcript is polyadenylated and translated on mitochondrial ribosomes.
