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.

DNA, which is stored in a cell’s nucleus, encodes the genetic information for making proteins. mRNA transfers a copy of this genetic information outside of the nucleus, to a cell’s cytoplasm, where it is translated into amino acids by ribosomes and then folded into … 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.

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.
