Messenger RNA (mRNA) serves as the vital intermediary in the "central dogma" of molecular biology, bridging the gap between stable genomic DNA and the production of functional proteins. Acting as a transient transcript, mRNA carries specific genetic instructions from the cell nucleus to the ribosome, where the code is translated into precise amino acid sequences.

That they did. The horror stories I could tell you. Mom was raised in nazi Germany, and the family was on watch list for helping the Americans. Anyhow, that's for another day.
