The transportation of information in a cell occurs in two steps. Firstly DNA (the information store) is transcribed into mRNA this is done by enzymes like RNA polymerase. This mRNA is then tranlated into proteins by the RIBOSOME (this is the organelle i think your asking about)
The rough endoplasmic reticulum is a network of membranes involved in the production of proteins. Protein synthesis occurs in the ribosomes, which are attached to the outside of the rough ER, giving it a 'rough' appearance.
