Question

Quizplus · Accepted Answer

Pre-rRNAs have more pseudouridine residues and methylated nucleotides than other RNA transcripts. Pseudouridine is the most common modified nucleotide found in RNA and it is known to stabilize RNA structures. Methylated nucleotides are also common in pre-rRNAs and are important for regulating RNA processing and ribosome biogenesis. Thymidine residues are not typically found in RNA, and pseudocytosines are not a well-characterized RNA modification.
