The maternal to zygotic transition (MZT) involves the transfer of genome regulation from the oocyte to the embryo and is essential for the formation of totipotent embryos. However, regulatory mechanisms are still poorly understood despite recent progress in mapping the dynamics in RNA transcripts and DNA methylation1-9. Previous studies suggest that dynamic histone modifications may play important roles in MZT10-12, however direct measurements of chromatin states has been hindered by technical d...

How this grade was computed

The insufficient grade is a transparent weighted average. Each metric below scored from 0–100% against the published ChIP-seq thresholds, weighted by its importance; nothing is hidden or subjective.
