Inside eukaryotic cells, you have a nucleus.

真中有一个。

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

大约 12.5 亿年前，一个真蚕食了另一个。

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

大多数是真生物——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生物，意味着我们的含有器。

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

但该系统已改造，可在许多物种和真中使用。

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

但些最早的真植物很快就动物吃掉了，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。

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可以操控，并在多种真生物及中运用。

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

所以最大的真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，人们认为生活在深海中的大多数真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.

们的没有来储存 DNA。不过，包括我们人类在内的所有植物和动物都是真生物。

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， 一个简单的吞噬另一个，形成共生关系， 并产生第一个真或具有内脏器官的。

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生物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.

生命终于拥有了变得有趣所需的所有成分：它有真，将成为复杂生物体的基石。

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

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.

与真相比，菌的结构简单很多：缺少及膜包的器，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生物中的器，它帮助提供能量、分化、生长和许多任务。

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.

由于些与生物体的相比有多大，以及些内部的一些不同结构， 们认为它是真生物——具体来说， 是一种红藻。
