small nucleolar RNA (snoRNA)

Small nucleolar RNA (snoRNA) are specialized RNA molecules found primarily in the nucleus of cells. They play a crucial role in the modification and processing of other RNA molecules, especially ribosomal RNAs (rRNAs), which are essential for making proteins. snoRNAs guide chemical changes, such as methylation and pseudouridylation, ensuring rRNAs develop correctly for proper protein synthesis. Think of snoRNAs as molecular editors that fine-tune the building blocks of the cell’s protein factory, maintaining cellular health and function.
