Post Transcriptional Modification Of Mrna. Post-transcriptional Modification Abulais Shomrat Genetics Leave a comment 460 Views The process of transcription is very similar in prokaryotes and eukaryotes but there are major differences in the relation between the transcript and the mRNA used for polypeptide synthesis in eukaryotes. Post-transcriptional modifications of pre-mRNA such as capping splicing and polyadenylation take place in the nucleus. The introns are cut out the exons are spliced together and a poly A tail and 5 cap are added. Post-transcriptional modification is a process in cell biology by which in eukaryotic cells primary transcript RNA is converted into mature RNA.

Post-transcriptional Modification The RNAs produced from transcription are called primary transcripts and are inactive. The identification and functional characterization of proteins that specifically recognize RNA N6-methyladenosine m6A unveiled it as a modification that cells utilize to accelerate mRNA metabolism and translation. Primary transcript hnRNA must be processed to produce the mRNA active form. 2 During post-transcriptional processing portions of the RNA chain that are not supposed to be translated into proteins are cut out of the sequence. After these modifications have been completed the mature mRNA molecules have to be translocated into the cytoplasm where protein synthesis occurs. The capping of the mRNA occurs in the nucleus and typically occurs prior to the completion of transcription of the mRNA.
The modification of the 5-ends of eukaryotic mRNA is called capping.

The modification of the 5-ends of eukaryotic mRNA is called capping. A notable example is the conversion of precursor messenger RNA into mature messenger RNA mRNA which includes splicing and occurs prior to protein synthesis. The cap is composed of a methylated GTP that is linked to the rest of the mRNA by a reverse 5 to 5 triphosphate bridge.
