It is single stranded and codes for 1 protein (although in bacteria one mRNA can code for many proteins). It is the actual bit that gets TRANSCRIBED in the nucleas (copied) and TRANSLATED (written) into proteins in the cytoplasm on ribosomes (which are incidently another form of RNA...rRNA). </span>
