"<h4>Role:</h4><span><p>DNA contains all the information needed for a life.</p></span>"+

"<h4>Operation:</h4><span><p>A strand of mRNA (messenger) pass through the ribosome and tRNA (transfer) between the large subunit where the codon (group of three nitrogen bases) is one who is in front of the mRNA.

"<h4>Role:</h4><span><p>Multiple, there are RNA transport, passenger, cruise, guides, satellite ...</p></span>"+

"<h4>Operation:</h4><span><p>Copying of genetic information, the opening of the double helix of DNA, and then copying the RNA codons. It can then exit the nucleus, the DNA can not do it.</p></span>"

"<h4>Operation:</h4><span><p>Creation of a ribosome: Transcription of rRNA and protein needed (this step is performed in the cytoplasm by other ribosomes) that fall within the nucleus, association of molecules frankly formed a new ribosome, which leaves the nucleus to play its role.</p></span>"
