Abstract

The kinetics of binucleate cells, formed by the action of deoxyguanosine, are studied using three methods: in a population synchronized with hydroxyurea, by autoradiography after pulse-labelling, and in a sample of a cell population morphologically located at the M--G1 limit. Deoxyguanosine induces a slowing down in S and G2, independent of the inhibition of cytokinesis. It is only when it takes effect during the G2 stage that deoxyguanosine brings about the formation of binucleate cells.
