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

大多数细胞生物——动物细胞、植物细胞和菌等。

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

植物和动物也都生物，这意味着我们的细胞含有细胞器。

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·卢卡斯认为这基于线粒体的概念，线粒体存于所有生物中的细胞器，它帮助提供能量、细胞分化、细胞生长和许多其他任务。

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.

与细胞相比，细菌的结构简单很多：缺少细胞及包被的细胞器，例如线粒体、内质网与高尔基体。

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：它有细胞，这将成为复杂生物体的基石。

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.

由于类固醇生物系谱中随处可见，因此人们认为它们存于所有现代生物的最后一个共同祖先中。

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

而且这个系统的基础部分可以被操，多种生物及细胞中运用。

Inside eukaryotic cells, you have a nucleus.

细胞中有一个细胞。

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

但这些最早的植物很快就被其他动物吃掉了，被劫持了珍贵的叶绿体，就像绿叶海天牛一样。

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

大约 12.5 亿年前，一个细胞蚕食了另一个细胞。

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

但该系统已被改造，可许多物种和细胞中使用。

So at some point, death was invented, you know, somewhere along the eukaryotic scale.

于，某个时刻，死亡被创造出来了，你知道的，大概生物的某个阶段。

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

所以最大的细胞我们中间的快乐地方。

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.

因为这些细胞与其它生物的细胞相比体积非常大，且细胞内部有一些独特的结构， 他们认为这的——具体来说， 一种红藻。

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.

想想生命的奇妙之处：我们现识别出了大约150万种物种，但可能有高达1000万种至今仍然存活。

It does seem like, correct me if I'm wrong, that we only made eukaryotic cells once, so that seems to have been a big jump.

确实看起来， 如果我错了请纠正，我们似乎只地球上进化出细胞一次，这似乎一个巨大的飞跃。

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了另一个细胞，形成了共生关系， 产生了第一个细胞， 即具有内部器官的细胞。

In other words, we use communication to sync single celled organisms with their environment and coordinate activities in eukaryotic cells.

换句话说，我们利用通信来使单细胞生物与其环境同步，细胞中协调活动。

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

事实上，人们认为生活深海中的大多数生物都具有生物发光能力。

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。
