-mRNA, like all RNA, is composed of four nucleic acids called bases, adenine (A), uracil (U), gaunine (G), and cytosine (C). RNA is created in a process called transcription.  During transcription an enzyme called RNA polymerase binds to specific region of DNA, a gene, and uses the DNA nucleic acid sequence as a template to make a shorter, single stranded RNA. <ref> Alberts, Bruce; Johnson, Alexander; Lewis, Julian; Raff, Martin; Roberts, Keith; Walter, Peter.

-During [[translation]], the mRNA then is decoded to make protein.  Combinations of three nucleic acids form a [[codon]].  Each codon corresponds with a specific [[amino acid]].  For example, the combination GAA codes for the amino acid glutamate.  The translation machinery "reads" the mRNA and strings together the correct amino acids to form a protein. <ref> Alberts, Bruce; Johnson, Alexander; Lewis, Julian; Raff, Martin; Roberts, Keith; Walter, Peter.
