WebPre-mRNA has to undergo at least two, and usually 3, processing steps before they can be exported to the cytoplasm as mature mRNA. These are, in order: The 5′ end of the pre-mRNA is modified by the covalent attachment of a 7-methylG nucleotide, called the 5′-cap. The 5′ cap is required for eukaryotic ribosomes to initiate translation. WebIn the nucleus, a pre-mRNA is produced through transcription of a region of DNA from a linear chromosome. This transcript must undergo processing (splicing and addition of 5' cap and poly-A tail) while it is still in the nucleus in order to become a mature mRNA. In contrast to introns, exons are the part of an mRNA transcript that actually contain …

WebIn the capping step of mRNA processing, a methylated-guanosine (7-methyl-G) is linked to the phosphates at the 5' end of the mRNA. The cap protects the 5' end of the mRNA from degradation by nucleases and also helps to position the mRNA correctly on the ribosomes during protein synthesis.
