223 x 3 = 669
Three nucleotides make up a codon, which encodes the amino acid.

usually the mRNA has three main parts:
1)the begining codon Uaually AUG
2)other codons
3) the ending codon (( UAG or UUA or UGA )) this part will have no amino acid made from it (the triky spot as i say!)
so we have 223 X 3 = 669
669+3=672 nuleotides

The coding region of the mRNA should contain 669 nucleotide residues. Apart from this, all eukaryotic mRNA will contain modified 5' end and 3'end.
