Summary

Automatic Translation

Oversættelse af ribosomer afkoder tre nukleotider pr. Codon til peptider. Deres bevægelse langs mRNA, fanget ved ribosomprofilering, producerer fodsporene, der udviser karakteristisk tripletperioditet. Denne protokol beskriver, hvordan du bruger RiboCode til at dechiffrere denne fremtrædende funktion fra ribosomprofileringsdata for at identificere aktivt oversatte åbne læserammer på hele transkriptomniveau.
