Ribosomal RNA Processing rRNA genes of both eukaryotes and bacteria are transcribed as larger precursors must be processed to yield rRNAs of mature size Several different rRNA molecules are embedded in a long, precursor and each must be cut out 16- Eukaryotic rRNA Processing Ribosomal RNAs are made in eukaryotic nucleoli as precursors that must be processed to release mature rRNAs Order of RNAs in the precursor is 18S 28S in all eukaryotes Exact sizes of the mature rRNAs vary from one species to another 16- Human Cells Processing 5’-end of 45S precursor RNA is removed to 41S 41S precursor is cut into 2 parts: 20S precursor of 18S 32S precursor of and 28S rRNA 3’-end of 20S precursor removed, yielding mature 18S rRNA 32S precursor is cut to liberate .
