Size distribution curves for budding yeasts. (A) Curve depicts a normal distribution curve with similar mean, median and mode values. (B) Curve depicts a size distribution curve for budding yeasts obtained in logarithmic phase. Unlike normal distributions, yeast cell size curves are usually skewed to the right where the mode is often the smallest value, since ~50% of the population is comprised of newly born daughter cells. Also, due to the asymmetric nature of cell division and exponential nature of cell growth, the mean value tends to be larger than the median. (C) Coulter counter curves for representative size mutants in the logarithmic phase: whi mutant (rpl36bΔ), wild-type (WT) and uge mutant (ctr9Δ).
