Abstract

A technique allowing chain formation by Escherichia coli for the analysis of the segregation of certain cellular components by autoradiographic methods has been developed. Deoxyribonucleic acid labeled with 3 H-thymidine does not appear to segregate preferentially with one or another of the bacteria. Membrane lipids labeled with either 3 H-oleate or 3 H-glycerol are evenly distributed among all progeny cells. A similar pattern of distribution of cell wall material is observed when 3 H-diaminopimelate is used as the marker.
