Small nucleolar RNAs
Small nucleolar RNAs (snoRNAs) are short RNA molecules found in the nucleus of cells. Their main role is to guide chemical modifications of other RNAs, particularly ribosomal RNAs (rRNAs), which are essential components of the cell's protein-making machinery. By directing these modifications, snoRNAs help ensure that rRNAs function correctly, contributing to proper protein synthesis. They act like molecular guides or editors within the nucleus, maintaining the health and efficiency of the cell's core processes.
