Post-transcriptional modification is a process in cell biology by which, in eukaryotic cells, primary transcript RNA is converted into mature RNA. A notable example is the conversion of precursor messenger RNA into mature messenger RNA (mRNA), which includes splicing and occurs prior to protein ...

Learning Outcomes Describe RNA post-transcriptional modification and its purpose Gene expression can be regulated at various stages after an RNA transcript has been produced. Some transcripts can undergoalternative splicing. This regulated process makes different mRNAs and proteins from the same initial RNA...
proteins and nucleotides. This process is controlled by specialized enzymes responsible for the addition or removal of each modification [17]. PTMs and their regulation constitute a cellular communication code to respond in a fast, versatile and accurate mode. The fulcrum of this review is that PT...
