Messenger RNA. Messenger RNA (mRNA), molecule in cells that carries codes from the DNA in the nucleus to the sites of protein synthesis in the cytoplasm (the ribosomes). The molecule that would eventually become known as mRNA was first described in 1956 by scientists Elliot Volkin and Lazarus Astrachan.
In eukaryotic organisms, mRNA is made in the nucleus, then exits the nucleus into the cytosol, where ribosomes will attach to it to create proteins.
