The random transition model of the cell cycle. A critical review.
The random transition model of the cell cycle has received much attention in recent years in attempts to describe and explain variations in cell cycle times. In this review we suggest statistical procedures for fitting the model to experimental data in place of the invalid techniques currently used. However, we also argue that there have been misconceptions about criteria for quality of fit of the model, and consequent biological interpretations. Other models fit just as well, and the analyses we describe do not provide evidence for any particular biological mechanism.
