WebSmall nucleolar RNAs (snoRNAs) are a class of small RNA molecules that guide chemical modifications ( methylation or pseudouridylation) of ribosomal RNAs (rRNAs) and other RNA genes ( tRNAs and other small nuclear RNAs (snRNAs)). They … Small nuclear RNA (snRNA) is a class of small RNA molecules that are found within the splicing speckles and Cajal bodies of the cell nucleus in eukaryotic cells. The length of an average snRNA is approximately 150 nucleotides. They are transcribed by either RNA polymerase II or RNA polymerase III. Their primary function is in the processing of pre-messenger RNA (hnRNA) in the nucleus. They have also been shown to aid in the regulation of transcription factors (7SK RNA) o…
