The figure is a representation of the processing of raw mRNA generated from transcription, otherwise known as pre-mRNA, to a standardized mRNA that can be translated.
<h3>Pre-mRNA processing</h3>
After transcription, the pre-mRNA produced needs to be processed and refined in order to be ready for translation.
The non-coding sequence, otherwise known as introns, are spliced out of the pre-mRNA and the coding sequence, the exons, are joined back together.
The whole process is mediated by different enzymes.
