现在的科技可以随意合成冗长的DNA链，这意味着我们已经能够复制病毒的基因组，而细菌基因组的复制也指日可待。

The ability to synthesise huge screeds of DNA at will means the genomes of viruses can be replicated already, and replicating those of bacteria is not far off.

它可促使DNA基因单链复制，这被称作信使RNA（mRNA），它会传递信息给细胞产生蛋白质。

It makes single-stranded copies of DNA’s genes, called mRNA, which tell the cell to produce proteins.
