And yet this kind of parental imprinting is very hard to spot — and therefore overcome.

但这种母的影子藏得深，以发现，因此也服。

This special genetic process is called imprinting, where only one copy of the gene gets expressed, not both.

这一特殊的遗学过程称为“印记”，印记基因的存在使得两个等位基因中的一个表达而另一个不表达。

' exclaimed Charlotte, imprinting a kiss upon his ugly face.

”夏洛特大声说，在他丑陋的脸上印下了一个吻。

' I stood there, letting the charge flow through me, the white flashes imprinting themselves on my eyelids.

’我站在那里， 让电荷流过我，白色的闪光在我的眼皮上留下印记。

Sometimes that methylation occurs on the paternal chromosome even when there's no imprinting center defect, and that's called an epimutation.

有时即使印记中心没有突变，源染色体也可以发生甲基化，这一过程称为表观突变。

Ducklings go through a rapid learning process called imprinting shortly after birth — it's what allows them to identify and follow their mothers.

鸭崽在出生后不久就会经历一种速的学习过程，称为印记行为——这让它们可以识别和跟随母亲。

Translocations can disrupt SNRNP and move the small nucleolar RNA genes away from their imprinting center, causing them to get methylated and turned off.

SNRNP基因易位会破坏小核内核糖核蛋白（SNRPN），并将核仁小RNA基因移出印记中心，导致这些基因的甲基化沉默。

Alright, as a quick recap, Prader-Willi syndrome is an imprinting disorder, where mutations on only the paternal copy of a chromosome causes the disease.

，速回顾一下：普拉德-威利综合征是一种印记病，仅在源染色体突变时发生。

If the paternal imprinting center is mutated, the region gets methylated and those genes get turned off, meaning that both the maternal and paternal genes are silenced.

如果源印记中心突变，基因将被甲基化沉默，导致母源和源基因都处于沉默状态。

A third way to get Prader-Willi syndrome, is a mutation in the imprinting center, which is a sequence of DNA near the Prader-Willi genes that directs imprinting via sex-specific methylation.

第三种导致普拉德-威利综合征的原因是印记中心的突变；印记中心是临近普拉德-威利基因的DNA序列，通过性别特异的甲基化介导印记。

With my " W" Blog, I'm imprinting proper etiquette and fashion sense as well as my philanthropic mandate on a whole new generation much like you did.

在我的" W" 博客里 我正在以全新的姿态写一些礼仪规范 时尚资讯以及我的慈善事业 就如您所做的一样。

Dating back to May 15, 2021, a lander, carrying the Zhurong rover, touched down in the southern part of Utopia Planitia, a vast plain in the northern hemisphere of Mars, imprinting the country's first landing on an extraterrestrial planet.

可以追溯到 2021 年 5 月 15 日，一个载有祝融号巡视器的着陆器在乌托邦平原的南部着陆（乌托邦平原是火星北半球的一个广阔平原），标志着我国首次登陆地球外的行星。

It used to be thought that there is some sort of magical moment of imprinting that when the baby is born, the baby must see his or her mother and " boom, " a connection is made.

过去人们认为， 有某种神奇的印记时刻， 当婴儿出生时，婴儿必须看到他或她的母亲， 然后“砰”的一声，一种联系就建立了。
