How cells measure themselves

Researchers found that cells regulate their own size by using DNA content as an internal scale. Cells with too little KRP4 delay DNA replication until they catch up, while those with too much dilute KRP4 to speed up the process. This mechanism keeps meristem cells within a narrow size range.
