Messenger ribose nucleic acid (mRNA) is the the type of RNA cells use to synthesis proteins.   

Messenger ribose nucleic acid (mRNA) is the the type of RNA cells use to synthesis proteins.   

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.
