We will see two special types of RNA: messenger RNA, which is known as mRNA, and transfer RNA, which is known as tRNA.

我们将看到两种特殊类型的 RNA：信使 RNA，称为 mRNA，和转运 RNA，称为 tRNA。

We have RNA messengers for the creation of protein, and then we have microRNA, controllers of this process.

我们有用于创建蛋白质的 RNA 信使，然后我们有 microRNA，这个过程的控制器。

To find out the researchers sequenced each cell's messenger RNA, which reflects active genes.

为了找出答案，研究人员对每个细胞的信使 RNA 进行了测序，它反映了活性基因。
