messenger RNA

Protein synthesis instructions

Messenger RNA, usually abbreviated mRNA, is the molecule that carries genetic instructions from DNA to the cellular machinery that builds proteins.

DNA serves as the master blueprint, but mRNA acts as the working copy—transcribed from DNA, then translated into proteins.

The term gained wide recognition during the COVID-19 pandemic, when mRNA vaccines introduced synthetic messenger RNA to trigger immune responses: The mRNA vaccines were developed with unprecedented speed.
