Abstract

Single Saccharomyces lactis cells taken from a random population were assayed for beta-D-galactosidase activity under a microscope equipped for fluorogenic measurements. The cells were also photographed, and enzymatic activity was correlated to the size of cell buds. A perodic pattern of enzyme synthesis was found during the cell cycle.
