Inside eukaryotic cells, you have a nucleus.

真核细胞中有一个细胞核。

Around 1.25 billion years ago, a eukaryotic cell cannibalized another cell.

大约 12.5 亿年前，一个真核细胞蚕食了另一个细胞。

Most cells are eukaryotic — animal cells, plant cells, and fungi, etc.

大多数细胞是真核——动细胞、植细胞和真菌等。

Plants and animals are also both eukaryotic organisms, meaning our cells contain organelles.

植和动也都是真核，意味着我们的细胞含有细胞器。

But the system has been altered for use in a variety of species and eukaryotic cells.

但该系统已改造，在许多种和真核细胞中使用。

But these first eukaryotic plants were soon consumed by other animals, which hijacked the precious chloroplast, just like Elysia.

但些最早的真核植很快就其他动吃掉了，并劫持了珍贵的叶绿体，就像绿叶海天牛一样。

" Diameter of a eukaryotic cell." Look at that, Soren.

" 真核细胞的直径" , 看看个, 索伦。

We're back to our—to our big, big eukaryotic cell.

我们回到了我们的大真核细胞。

But the basic parts of this system can be manipulated and used in a variety of eukaryotic organisms and cell types.

而且个系统的基础部分操控，并在多种真核及细胞中运用。

So the biggest eukaryotic cell is our happy place in the middle.

所最大的真核细胞是我们在中间的快乐地方。

In fact, it's thought that the majority of eukaryotic life that lives in the deep sea has bioluminescent capabilities.

事实上，人们认为活在深海中的大多数真核都具有发光能力。

Their cells don’t have a nucleus to store DNA. All plants and animals, including us humans, are eukaryotic, though.

他们的细胞没有细胞核来储存 DNA。不过，包括我们人类在内的所有植和动都是真核。

At 1pm, a simple cell engulfs another, creating a symbiotic relationship and the first eukaryotic cells, or cells with internal organs.

下午 1 点， 一个简单的细胞吞噬另一个细胞，形成共关系， 并产第一个真核细胞或具有内脏器官的细胞。

Because sterols are found throughout the eukaryotic family tree, they are thought to have been present in the last common ancestor of all modern eukaryotes.

由于类固醇在真核系谱中随处见，因此人们认为它们存在于所有现代真核的最后一个共同祖先中。

Life finally had all the ingredients that it needed to get interesting: It had eukaryotic cells, which would become the building blocks of complex organisms.

命终于拥有了变得有趣所需的所有成分：它有真核细胞，将成为复杂体的基石。

However, genomic libraries may be an inefficient method of finding a gene, particularly in large eukaryotic genomes, where much of the DNA is noncoding.

替代的方法是利用已知表达目的基因的细胞或组织来源的mRNA所构建的文库。

However, often the overproduced proteins, which could represent up to 30% of total cell protein, were precipitated or insoluble and they lacked eukaryotic post-translational modifications.

有时，些问题能通过合成融合蛋白随后在裂开得到目的蛋白的方法得到解决，但是随后采取真核细胞（酵母或者哺乳动细胞系）更为简单行。

When compared to eukaryotic cells, the structure of bacteria is less complex due to a lack of nucleus and membrane-bound organelles such as mitochondria, endoplasmic reticulum, and Golgi complexes.

与真核细胞相比，细菌的结构简单很多：缺少细胞核及膜包的细胞器，例如线粒体、内质网与高尔基体。

George Lucas has suggested that this was based on the idea of mitochondria, an organelle found in all eukaryotic organisms that helped supply energy, cellular differentiation, cell growth, and many other tasks.

乔治·卢卡斯认为是基于线粒体的概念，线粒体是存在于所有真核中的细胞器，它帮助提供能量、细胞分化、细胞长和许多其他任务。

Because of how big those cells are compared to the cells of other organisms, and some distinct structures inside those cells, they think it’s eukaryotic – specifically, a kind of red algae.

由于些细胞与其他体的细胞相比有多大，及些细胞内部的一些不同结构， 他们认为它是真核——具体来说， 是一种红藻。
