Cell cycle of Saccharomycescerevisiae in populations growing at different rates.

Abstract

The cell cycle of Saccharomyces cerevisiae in populations growing at different rates was analyzed by flow microflourometry. The results demonstrate that (i) variation in growth rate of the population depends mainly on variation in the G1 phase of the cell cycle, and (ii) atall growth rates initiation of DNA synthesis occurs concomitantly with initiation of budding.
