WebI've always understood that they are near simultaneous. The important fact is that the primary RNA transcript (pre-mRNA) must have the Introns spliced out (splicing phase), and have the 5' cap and 3' Poly-A tail added (Protection phase) to become true mRNA. WebTranscription is the first step in gene expression. It involves copying a gene's DNA sequence to make an RNA molecule. Transcription is performed by enzymes called RNA polymerases, which link nucleotides to form an RNA strand (using a DNA strand as a template). Transcription has three stages: initiation, elongation, and termination. moxa tsn-g5004
