1 rich Libsyn https://www.libsyn.com 300 600 Early stages of drosophila development are marked by rapid cell cycles that go directly from S phase to mitosis without any obvious gap phases. Having previously investigated the role that cyclins play in timing these divisions, McCleland et al. now look at the role that S phase plays in regulating cell cycle progression. This episode of biosights presents two papers by McCleland et al. from the March 9, 2009 and October 5, 2009 issues of the Journal of Cell Biology and includes interviews with authors Mark McCleland and Patrick O’Farrell. Produced by Eun Choi. &amp;nbsp; Subscribe to biosights via iTunes or RSS View biosights archive The Rockefeller University Press biosights@rockefeller.edu biosights http://www.jcb.org/biosights <iframe title="Libsyn Player" style="border: none" src="//html5-player.libsyn.com/embed/episode/id/5957337/height/300/theme/custom/thumbnail/yes/direction/forward/render-playlist/no/custom-color/88AA3C/" height="300" width="600" scrolling="no" allowfullscreen webkitallowfullscreen mozallowfullscreen oallowfullscreen msallowfullscreen></iframe> https://assets.libsyn.com/secure/item/5957337
