This shows the cell nucleus disintegrating into fragments.

这显示是解体成碎片。

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

而人死之后，死亡，就开始分裂。

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

RNA分子是内双螺旋DNA基因单链拷贝。

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 在外蛋白质生中发挥作用很有限。

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

然后 mRNA 从进入质，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.

他们利用电将乳腺转移到第二只绵羊卵中。

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

然后，成体卡在卵中，基本上取代了卵。

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

它职能之一是充当信使将遗传信息从运送至制造蛋白质机器--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起源方面迈出了一大步，真生物是包括植物、动物和其他有生物群体。

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.

大多数中都有自己DNA，而线粒体DNA中有自己基因组，这与菌更相似。

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.

虽然动物大部分基因都包含在位于内染色体中，但 amh 基因仍然分开，在内自由浮动。

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、植物等祖先共生菌，所以线粒体有自己 DNA， 与中 DNA 分开。
