A lot of ancient fossils contain evidence of prokaryotic life, like bacteria.

许多古代化石都包含原核生物，如细菌。

The cDNAs had to be linked to prokaryotic transcription and translation signals and inserted into multicopy plasmids.

然而，占总蛋白30%过量表达蛋白质是沉淀或不溶形式并且缺少翻译后修。

Alright, as a quick recap, the bacteria are prokaryotic cells that play an important role in human disease and health and can be found almost anywhere in the environment.

得！快速回顾一下：细菌是一种在人类健康与疾病发生中有重要作用原核细胞，在我们生境中无处不在。

On the other hand, prokaryotic organisms like bacteria lack organelles, so their cellular contents are a little more willy-nilly, like that junk drawer where you keep the chip clips and sauce packets.

另一方面，像细菌这样原核生物缺乏细胞器，所以它们细胞内容物有点杂乱无章，就像你放薯片夹和酱包垃圾抽屉一样。
