Small nucleolar RNAs (snoRNAs)

Small nucleolar RNAs (snoRNAs) are a type of RNA found in the cell nucleus that play a crucial role in the processing and modification of ribosomal RNA (rRNA), which is essential for protein synthesis. They help guide chemical changes to rRNA, ensuring it functions correctly and is properly assembled into ribosomes, the cellular machinery that builds proteins. By facilitating these modifications, snoRNAs are vital for maintaining the overall health and efficiency of cellular function, impacting processes like growth and metabolism.
