Inside eukaryotic cells, you have a nucleus.

真核中有一个核。

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

大约 12.5 亿年前，一个真核蚕食了另一个。

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

大多数是真核生物——动物、植物和真菌等。

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

植物和动物也都是真核生物，意们含有器。

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

但该系统已被改造，可在许多物种和真核中使用。

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

但些最早真核植物很快就被其他动物吃掉了，并被劫持了珍贵叶绿体，就像绿叶海天牛一样。

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

" 真核直径" , 看看个, 索伦。

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

们回到了们大真核。

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

所以最大真核是们在中间快乐地方。

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

而且个系统基础部分可以被操控，并在多种真核生物及中运用。

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

事实上，人们认为生活在深海中大多数真核生物都具有生物发光能力。

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

他们没有核来储存 DNA。不过，包括们人类在内所有植物和动物都是真核生物。

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， 一个简单吞噬另一个，形成共生关系， 并产生第一个真核或具有内脏器官。

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.

由于类固醇在真核生物系谱中随处可见，因此人们认为它们存在于所有现代真核生物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.

生命终于拥有了变得有趣所需所有成分：它有真核，将成为复杂生物体基石。

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

替代方法是利用已知表达目基因或组织来源mRNA所构建文库。

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以得到目蛋白方法得到解决，但是随后采取真核（酵母或者哺乳动物系）更为简单可行。

Think of the wonder of life: We now recognize about 1.5 million eukaryotic species but there may be as many as 10 million alive today.

想想生命奇迹：们现在认识到大约 150 万种真核生物，但今天活可能多达 1000 万种。

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.

与真核相比，菌结构简单很多：缺少核及膜包被器，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概念，线粒体是存在于所有真核生物中器，它帮助提供能量、分化、生长和许多其他任务。
