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. WebUnderstand the difference between pre-mRNA and mRNA. After transcription, eukaryotic pre-mRNAs must undergo several processing steps before they can be translated. …

WebPre-mRNA is the first form of RNA created through transcription in protein synthesis. The pre-mRNA lacks structures that the messenger RNA (mRNA) requires.
