mRNA

n. RNA that transmits information from DNA in the nucleus to the ribosome sites of protein synthesis in the cell

Messenger Ribonucleic Acid (mRNA) is a molecule of RNA encoding a chemical "blueprint" for a protein product. mRNA is transcribed from a DNA template, and carries coding information to the sites of protein synthesis: the ribosomes. Here, the nucleic acid polymer is translated into a polymer of amino acids: a protein. In mRNA as in DNA, genetic information is encoded in the sequence of four nucleotides arranged into codons of three bases each. Each codon encodes for a specific amino acid, except the stop codons that terminate protein synthesis. This process requires two other types of RNA: Transfer RNA (tRNA) mediates recognition of the codon and provides the corresponding amino acid, while Ribosomal RNA (rRNA) is the central component of the ribosome's protein manufacturing machinery.
