H4K20me kinetics in normal and cell-cycle-arrested Xenopus embryos. This quantitative model invokes specific methylation and unspecific demethylation and correctly predicts cell-cycle durations and cell-cycle dependencies. Active demethylation is not required to explain H4K20me kinetics of cycling cells, suggesting that overall H4K20me dilution through DNA replication is dominant. So only once cells stop cycling during embryogenesis, active H4K20 demethylation may contribute to shape histone methylation.
