Messenger RNA
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.
