<em><u>Gene expression is the process by which genetic information carried by DNA are converted from genes via messenger RNA to proteins. </u></em>
<u><em>mRNA is the molecules that links genes to proteins. The mRNA is formed through the process of transcription from a gene strand. The mRNA is then translated into protein by the joint action to transfer RNA and the ribosome. </em></u>
<em><u>mRNA therefore, serves as a temporary copies of information found in the DNA. Thus, and mRNA represents an exact copy of the gene and it is put together using base pairing rules.</u></em>
