Recent work has highlighted its remarkable mode of synthesis by the ribonucleoprotein reverse transcriptase, telomerase<sup>1–4</sup>, as well as its ability to form unusual structures <i>in vitro</i>. Moreover, telomere synthesis by telomerase has been shown to be essential for telomere maintenance and long-term viability.</p></div></div></section> <div class="js-context-bar-sticky-point-mobile"
