This shows the cell nucleus disintegrating into fragments.

这显示的是细胞核解体成碎片。

Cells die and the cell nucleus begins to break apart after death.

而人死之后，细胞死亡，细胞核就开始分裂。

RNA molecules are single-stranded copies of the double-helical DNA genes in the cell nucleus.

RNA分子是细胞核内的双螺旋DNA基因的单链拷贝。

Normally, TDP-43 can also have a limited role outside of the cell's nucleus in protein production.

常情况下，TDP-43 在细胞核外蛋白质的生中发挥的作用很有限。

The mRNA then travels from the cell nucleus and out into the cytoplasm, until it reaches and attaches to a ribosome.

后 mRNA 从细胞核进细胞质，直到到达并附着在核糖体上。

Using electricity, they transferred the mammary gland cell's nucleus into an egg cell from a second sheep.

他们利用电将乳腺细胞的细胞核转移到第二只绵羊的卵细胞中。

Then, the adult cell’s nucleus gets stuck into the egg cell essentially replacing the egg cell’s nucleus.

后，成体细胞的细胞核卡在卵细胞中，基本上取代了卵细胞的细胞核。

One of its jobs is to act as a messenger carrying genetic information from a cell's nucleus to the machinery which makes proteins.

它的职能之一是充当信使将遗传信息从细胞核运送至制造蛋白质的机器--核糖体。

This year, microbiologists took a major step toward understanding the origin of eukaryotes, the group that includes plants, animals, and other organisms with cell nuclei.

今年，微生物家在解真核生物的起源方面迈出了一大步，真核生物是包括植物、动物和其他有细胞核的生物的群体。

And while most of your cells have their own DNA in the cell nucleus, mitochondria actually have their own genome in DNA, which is more similar to a bacteria.

大多数细胞的细胞核中都有自己的DNA，而线粒体的DNA中有自己的基因组，这与细菌更相似。

While most of an animal's genes are contained in chromosomes located inside the nuclei of cells, the amh gene remains apart, floating freely within the cell nucleus.

虽动物的大部分基因都包含在位于细胞核内的染色体中，但 amh 基因仍分开，在细胞核内自由浮动。

Because they derive from bacteria that became symbiotic about 2bn years ago with cells ancestral to animals, plants and so on, mitochondria have their own DNA, separate from that in a cell's nucleus.

因为它们源自大约 20 亿年前与动物、植物等祖先的细胞共生的细菌，所以线粒体有自己的 DNA， 与细胞核中的 DNA 分开。
