It's coded so that each three nucleotides (a codon) corresponds to at least one amino acid. In eukaryotic cells, as soon as precursor mRNA (pre-mRNA) has been transcribed from DNA, it is processed to mature mRNA. This removes its introns-non-coding sections of the pre-mRNA. The mRNA is then exported from the nucleus to the cytoplasm, where it's certain to ri...
