DNA methylation in post-mitotic neurons is reported to serve a variety of functions from
survival during development to the consolidation of memory.

In post-mitosis differentiating cells，where dnmt1is dominantly expressed in the nucleus，the half life of nuclear dnmt1 mRNA and protein is 1.5 hours and 4.5 hours respectively. Inthese cells，the rate of dnmt1 mRNA transcription is not different during the mitotic and post-mitotic periods.The rate of nuclear degradation of DNMT1 mRNAand protein increases by three fold as a cell transitions from a growing mitotic cell（low degradation）to a post-mitotic differentiating cell（high degradation）.
请大家翻译一下：post-mitotic neurons ，post-mitosis differentiating cells，during the mitotic and post-mitotic periods.
之前园子里有前辈翻译“post-mitotic ”为“不再增殖”；我希望确认一下，感谢！
