Box C/D snoRNAs

Box C/D snoRNAs are a type of small RNA molecules found in cells that help guide chemical modifications of other RNA molecules, particularly ribosomal RNA (rRNA). They are characterized by conserved sequence motifs called "boxes" C and D, which are essential for their function. These snoRNAs are part of larger complexes that attach to specific sites on rRNA and direct methylation, a chemical change that stabilizes rRNA structure and ensures efficient protein synthesis. By guiding these modifications, box C/D snoRNAs play a crucial role in maintaining proper cellular function and protein production.
