它很容易提取，因为它是在细胞核之外、叫做线粒体的结构里被发现的少量基因之一。

It is easily extracted, because it is one of a handful of genes found outside the cell nucleus, in structures called mitochondria.

结合物的细胞核基因是人类的，但是一小部分其它基因（位于细胞核外的称为线粒体的组织里面）来自兔子的遗传。

The nuclear genes of the result would be human, but a handful of other genes, which inhabit structures outside the nucleus, called mitochondria, would be inherited from the rabbit.

尽管此前已完成了美洲乳齿象的线粒体dna测序，研究者表示他们还首次实现了对细胞核dna的测序-在本例中使用的材料来自牙齿。

Although mastodon mitochondrial DNA has been sequenced before, the researchers say they were the first to do the analysis on DNA from the cell nucleus - in this case, using material from a tooth.

A human cell shown here on the opposite side has these formed organelles that I talked about a minute ago, mitochondria, Golgi, endoplasmic reticulum, nucleus.

另一边展示的是人类细胞,它带有我一分钟前讲过的成形的细胞器,线粒体,高尔基体,内质网,细胞核
