What role does RNA play in the flow of information at the cellular level?

It transfers information by transcription, which is the process of DNA "unzipping" to allow RNA to copy a piece of code. Usually that code is used to manufacture proteins which are essential to life.

RNA is a key player in the flow of cellular (genetic) information. Messenger RNA (mRNA) is produced during transcription, providing a set of instructions, copied from the gene in question, for the synthesis of proteins. Transfer RNA (tRNA) provides the context information at the ribosome when an mRNA molecule is being translated. The tRNA molecules match up with each codon of the mRNA providing the required amino acid for the protein chain to be synthesized.

shaun hit it right on the head. RNA is the transcription of the blue print of your DNA.
