This shows the cell nucleus disintegrating into fragments.

这显示的是细解体成碎片。

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

而后，细亡，细就开始分裂。

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.

正常情况下，TDP-43 在细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.

然后 mRNA 从细进入细质，直到到达并附着在糖体上。

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的细移到第二只绵羊的卵细中。

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

然后，成体细的细卡在卵细中，基本上取代了卵细的细。

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

它的职能一是充当信使将遗传信息从细运送至制造蛋白质的机器--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，微生物学家在理解真生物的起源方面迈出了一大步，真生物是包括植物、动物和其他有细的生物的群体。

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.

大多数细的细中都有自己的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.

虽然动物的大部分基因都包含在位于细内的染色体中，但 amh 基因仍然分开，在细内自由浮动。

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、植物等祖先的细共生的细菌，所以线粒体有自己的 DNA， 与细中的 DNA 分开。
