<p class="MsoNormal" align="left"><span lang="EN-US">In molecular genetics, an untranslated region refers to either of two sections, one on each side of a coding sequence on a strand of mRNA. If it is found on the 5' side, it is called the 5' UTR (or leader sequence), or if it is found on the 3' side, it is called the 3' UTR (or trailer sequence).</span><span lang="EN-US"><br />

More specifically, it is the set of expressed proteins in a given type of cell or organism, at a given time, under defined conditions.</span><span lang="EN-US"><br />
