RNA molecules play crucial roles in various cellular functions:
Protein synthesis: mRNA conveys genetic information from DNA, guiding the assembly of amino acids into proteins. Gene regulation: miRNA and siRNA regulate gene expression by degrading or blocking the translation of target mRNAs. RNA splicing: snRNA is involved in the removal of introns and joining of exons to generate mature mRNA. Catalytic activity: Ribozymes are RNA molecules with enzymatic functions, such as the ribosome's role in peptide bond formation.
