<p> However, RNA undergoes many different procedure, it gets its own properties.</p>
<h1p> mRNA include genetic information, codon. By the sequenced codon, ribosomes translate the mRNA into protein.</h1> <h1> </h1p>
<h1p> During the transcription and the translation, many regulation mechanism is existed to control the amount of expression of genome.</h1p>
