For the genes DNA to subsequently influence an inherited trait, the stored genetic information in the DNA in most cases is first transferred to a closely related nuclei acid, RNA or ribonucleic acid. In eukaryotic organisms, RNA most ofther carries the genetic information out of the nucleus, where chromosomes reside into the cytoplasm of the cell.
