Work is already under way to develop principles for editing reproductive cells.

编辑生殖细胞的原则制工作已经开始。

What's the difference between a gamete and a zygote?

生殖细胞和受精卵的区别是什么？

Another, they're releasing reproductive cells called spores.

后来，它们又释放一种叫做孢子的生殖细胞。

Its stable temperature and high density help preserve and disperse reproductive cells.

的温度和较高的密度有助于保存和分散生殖细胞。

" FYI this is probably the first human germ line editing, " Dr. Quake wrote.

“谨供参考：这可能是人类生殖细胞的首次编辑，”奎克写道。

So, a germ cell ovarian cancer refers to situations where these precursor germ cells become cancerous and form tumors.

因此，卵生殖细胞癌就是指位于卵的生殖细胞癌变形成的肿瘤。

Some originate from ovarian germ cells, such as mature cystic teratomas, also called dermoid cysts.

有的起源于卵生殖细胞，例如成熟的囊性畸胎瘤，又名皮样囊肿。

Many algae, for example, have sex cells that are indistinguishable in size.

例如，许多藻类的生殖细胞大小难以区分。

Unless land organisms return to the water to reproduce or have specially adapted sex cells, their options are limited.

除非陆地生物回到水中繁殖或有特别适应的生殖细胞，否则它们的择是有限的。

It does not always involve strictly female and male individuals with differently sized sex cells that fuse internally.

它并不总是严格涉及拥有不同大小内部融合的生殖细胞的女性和男性个体。

Histologically, prominent features include large, round tumor cells resembling germline tumors; or small cells forming Homer-Wright rosettes.

松果体瘤主要的组织学特征包括类似生殖细胞肿瘤中巨大圆形的肿瘤细胞，或是形成Homer-Wright菊形团的小细胞。

However, each reproductive cell has only 23 individual chromosomes.

然而，每个生殖细胞只有 23 条独立的染色体。

And, each follicle is made up of a germ cell, also known as an oocyte, which is the immature egg.

每一个卵泡都由一个生殖细胞组成，也就是卵母细胞，就是未成熟的卵子。

These are the most common germ cell tumor in children, and the tumors can be very aggressive.

这是最常发生于儿童身上的生殖细胞瘤，肿瘤侵袭性较强。

The other option is the sister chromatids of the x chromosome don't separate in meiosis two in the female germ cell.

女性生殖细胞中，X染色体姐妹染色单体在第二次减数分裂时没有分离。

Ferns, for example, reproduce from spores and need damp environments for their reproductive cells to reach each other.

例如，蕨类植物从孢子中繁殖，它们的生殖细胞需要潮湿的环境才能相互接触。

The macronucleus controls the non-reproductive cell functions, like eating, movement, and digestion and the micronucleus is necessary for reproduction.

大核控制非生殖细胞功能，如进食、运动和消化， 而微核是繁殖所必需的。

This happens around half-moons, when weaker tides calm the water's surface, creating the perfect conditions for their sex cells to couple up.

这发生在半月时候，当较弱的潮汐让海面平静，为它们的生殖细胞配对创造了完美的条件。

The genome of that germ cell would be permanently edited, and so would all of the cells in the

该生殖细胞的基因组将被永久编辑， 所有细胞中的细胞也将被永久编辑。

The idea that one scientist could make the leap towards editing reproductive cells has been condemned, but it has not been ruled out.

一位科学家可在编辑生殖细胞方面取得很大进步的这种观点遭到谴责，但并没有被完全否。
