Below Is a List of Steps in the Processing of Ribosomal

Below is a list of steps in the processing of ribosomal RNAs. Please select the choice that lists the steps in the CORRECT sequential order. 1. Methyl groups added to specific bases and the 2'-carbon atom of some ribose sugars
2) Transcription of the rRNA precursors from DNA
3) Cleavage of precursor rRNA
4) Individual rRNA molecules ready for ribosome assembly
5) Trimming of precursor rRNA
