In eukaryotic cells, mature mRNA is transported from the nucleus to the cytoplasm through nuclear pores. This process is facilitated by a cap-binding protein complex that binds to the 5′ cap of the mRNA. The cap-binding complex interacts with nuclear pore receptors, ensuring efficient recognition and export of the mRNA through the nuclear pore. These interactions are critical for the successful delivery of mRNA to the cytoplasm, where it can be translated into protein.The processing of pre-mRNA includes splicing, during which introns are removed, leaving only exons in the mature mRNA. If hybridization is performed between the initial mRNA transcript (pre-mRNA) and the DNA template, introns appear as loops because they are transcribed but not present in the mature mRNA. Only exons are translated into proteins, ensuring the fidelity of gene expression.What is the role of the cap-binding protein complex and mRNA splicing in eukaryotic cells?
