Messenger ribonucleic acid (mRNA)'s a molecule of RNA encoding a chemical "blueprint" for a protein product. mRNA's transcribed from a DNA template, and carries coding information to the sites of protein synthesis: the ribosomes. Here, the nucleic acid polymer's translated into a polymer of amino acids: a protein. In mRNA as in DNA, genetic information's encoded in the sequence of nucleotides arranged into codons consisting of three bases each. Each codon encodes for a specific amino acid, exce… (More on Mrna)
