Transcriptomes - Study guides, Class notes & Summaries

Pre-mRNA is the initial processing byproduct of mRNA transcription and is crucial for the expression of genes in mammalian cells, since the majority of protein-coding genes are broken by intermediate regions (introns) (Han et al., 2011). Part 1 The first and initial action in the pre-mRNA processing is the addition of an mRNA cap at the 5' end. Once the RNA's initial 20–30 nucleotides have been created, capping takes place. According to Cohen, 7- methylguanosine residue is added to the...
