Pre-mRNA splicing is, by definition, a co- or post-transcriptional RNA processing reaction by which introns are removed from mRNA precursors, and exons are precisely joined together to form functional mature mRNAs (Berget et al., 1977; Chow et al., 1977; Shi, 2024).The fidelity of this mechanism is critical for correct gene expression …

WebStep 1: Initiation. Initiation is the beginning of transcription. It occurs when the enzyme RNA polymerase binds to a region of a gene called the promoter. This signals the DNA to unwind so the enzyme can ‘‘read’’ the bases in one of the DNA strands. The enzyme is now ready to make a strand of mRNA with a complementary sequence of bases.
