This is thought to protect the message. Eukaryotic messages contain a tail of poly A. a. A string of A's is put on by a polymerase that doesn't need a template. Polyadenylation probably stabilizes the mRNA and makes it more transportable from nucleus to cytoplasm. H. Translation 1.
Translation is the process of making the primary sequence of proteins from the amino acids.
The translation apparatus consists of tRNAs and ribosomes. Amino acyl tRNAs place the correct amino acid into the growing polypeptide by codon-anticodon base pairing. Translation begins at the first AUG after the cap and establishes a reading frame. Disruption of the reading frame creates a frameshift mutation.
