mRNA (Messenger RNA)
Definition
mRNA is a type of RNA that carries instructions from DNA for controlling the synthesis of proteins.
Analogy
Consider mRNA as a courier service. It picks up messages (instructions for making proteins) from DNA at its home base (the nucleus) and delivers them to their destination (ribosomes).
