Intron removal, or RNA splicing, is a crucial post-transcriptional process that involves the excision of non-coding sequences, called introns, from pre-mRNA molecules. This process is essential for producing mature mRNA transcripts that can be translated into functional proteins, ensuring gene expression is accurately regulated.

RNA splicing is a critical process in eukaryotic gene expression where introns are removed from pre-mRNA and exons are joined to form mature mRNA. This process allows for the generation of multiple protein isoforms from a single gene through alternative splicing, contributing to proteomic diversity.

Gene expression is the process by which information from a gene is used to synthesize a functional gene product, typically proteins, which ultimately determine cellular function and phenotype. This process is tightly regulated at multiple levels, including transcription, RNA processing, translation, and post-translational modifications, to ensure proper cellular function and response to environmental cues.
