Just to clarify the “messenger” thing: mRNA is called like that because it delivers the message (i.e. the instructions to produce a protein) between the genome and the ribosome. The denomination is also useful to distinguish it from other, usually non-coding (meaning “not blueprints for proteins”) types of RNA.
