SMALL NUCLEAR RNA Meaning and
Definition
-
Small nuclear RNA (snRNA) is a type of ribonucleic acid molecule that plays a crucial role in the process of gene expression and the maturation of messenger RNA (mRNA) molecules in eukaryotic cells. It is a short RNA molecule, typically ranging from 100 to 300 nucleotides in length.
The primary function of small nuclear RNA is to form ribonucleoprotein particles known as small nuclear ribonucleoproteins (snRNPs). These snRNPs are involved in the spliceosome complex, which is responsible for removing intronic sequences from pre-mRNA during RNA splicing. In other words, snRNA acts as a guide or scaffold to bring together the snRNP proteins to form the functional spliceosome, enabling the removal of non-coding regions and the joining of exons to generate mature mRNA.
Due to its involvement in RNA processing, snRNA is a crucial component in regulating gene expression. It ensures the proper removal of introns, which allows for the synthesis of functional proteins encoded by exons.
Overall, small nuclear RNA plays a crucial role in the intricate process of gene expression by facilitating the splicing of pre-mRNA molecules. It is a key component in the formation of snRNPs and spliceosomes, effectively enabling the generation of mature mRNA transcripts essential for proper protein synthesis in eukaryotic cells.
