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.

WebDuring this process, the DNA sequence of a gene is copied into RNA. Before transcription can take place, the DNA double helix must unwind near the gene that is getting transcribed. The region of opened-up DNA is called a transcription bubble. Transcription uses one of the two exposed DNA strands as a template; this strand is called the template ... WebOct 12, 2024 · Pre-mRNA splicing or alternative splicing is one of the most important mechanisms in post-transcriptional regulation. Pre-mRNA splicing promotes protein diversity in an organism because multiple, mature mRNAs containing different exons can be generated from a single gene and translated to distinct but functionally similar proteins …
