By pre-mRNA I assume is meant the initial RNA transcript before splicing. There is no reason why an intron that is spliced out so that it does not appear in the final mRNA should not contain start or stop codons, which if not removed would have altered the reading frame.

WebIn eukaryotic cells, how does a pre-mRNA differ from a mature mRNA? a. Explain the purpose of each of the three pre-mRNA processing events. b. Give the order in which these events occur. c. Specify the pre-mRNA region involved in each event. d. State where in the eukaryotic cell these processes occur. Show transcribed image text Expert Answer WebThe major difference between pre-mRNA and mRNA is that pre-mRNA is the immediate product of transcription which is comprised of both exons (coding sequences) and introns (non-coding sequences). After transcription pre-mRNA is spliced, which involves the removal of introns by spliceosomes resulting in the formation of mature mRNA. ipc 429 hindiWebApr 12, 2024 · “@elonmusk @BillyM2k How does mRNA tech differ from CRISPR?” openssl view pem certificate
