The precursor mRNA or pre-mRNA is the primary transcript in the transcription process. It has both exons (coding sequence) and introns (non-coding sequence). Initially, it is produced from a DNA sequence inside the nucleus by transcription. It undergoes many processing stages before being converted into … See more mRNA is a single-stranded RNA that is created during transcription.

WebJun 9, 2024 · In these organisms, transcription of DNA produces pre-mRNA. These pre-mRNA transcripts often contain regions, called introns, that are intervening sequences which must be removed prior to translation by the process of splicing.

WebmRNA editing adds a 3′ poly-A tail, but mRNA processing does not. 5′ Capping While the pre-mRNA is still being synthesized, a 7-methylguanosine cap is added to the 5′ end of the growing transcript by a phosphate linkage. This moiety (functional group) protects the nascent mRNA from degradation. 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.
