A ribosome is a complex organelle consisting of several rRNA molecules and many proteins. Each functional ribosome consists of a large and a small subunit. Ribosomal RNAs in both bacterial and eukaryotic cells are modified after transcription. In eukaryotes, rRNA processing is carried out by small nucleolar RNAs.
-What types of changes take place in rRNA processing?
A) Methylation of bases
B) Cleavage of a larger precursor
C) Nucleotides are trimmed from the ends of rRNAs.
D) All of the above
