The Pennsylvania State University. As discussed previously, eukaryotic mRNAs are capped at their 5' end and polyadenylated at their 3' end. In vitro assays for these reactions have been developed, and several of the enzymatic activities have been identified. These will be reviewed in this section. Polyadenylation is not limited to eukaryotes.Messenger RNA 3′ end processing is a well-orchestrated process that involves components of the transcription, the splicing and the translation machinery. The medical importance of 3′ end processing is illustrated by an increasing number of different disease entities, which are caused by inappropriate 3′ end processing. Cells decode mRNAs by reading their nucleotides in groups of three, called codons. Here are some features of codons: Most codons specify an amino acid. Three "stop" codons mark the end of a protein. One "start" codon, AUG, marks the beginning of a protein and also encodes the amino acid methionine.
