genetic imprinting

基本解释

Objective: CTCF is a multifunctional transcription factor, which plays many roles in promoter regulation, insulator function and genetic imprinting.
目的：CTCF是一种多功能的转录因子，参与启动子调控、绝缘子功能和遗传印记等过程。
However, what science told us back in 1984 was that human females certainly could never have a natural virgin birth, because of a genetic barrier in mammals called imprinting.
然而1984年时候的科学去告诉我们，由于哺乳动物中存在被称作印记的基因障碍，所以说女性是绝不可能进行处子生育的。
Conclusion Parental specific expression exists in the transmission of tic disorder, which gives evidence that genomic imprinting may be involved in the genetic mechanism of tic disorder.
结论抽动障碍的传递存在亲源特异性表达，抽动障碍病因学中可能存在遗传印迹机制。

The barrier to parthenogenesis in mammals, it seems, is something known as genetic imprinting.
ECONOMIST: A “virgin birth” in mice
There appears, in particular, to be a problem with a phenomenon known as genetic imprinting.
ECONOMIST: Cloning around
In very young eggs all the genetic imprinting has been erased—a state much closer to a paternal genome.
