The medicine does this by inhibiting T and B cell DNA synthesis, preventing them from replicating.

透过抑制T和B淋巴细胞的遗传物质 - DNA - 的生成， 使它们无法进行细胞分裂。

I totally agree with that -- that it would be desirable, for example, maybe to have DNA synthesis machines, not as a product where each lab has their own device, but maybe as a service.

注意：我完全同意这一点——例如，可能有 DNA 合成机器是可取的， 而不是作为每个实验室都有自己设备的产品，而是作为一种服务。
