I am not just saying "plastic" means "polymer," right, but nevertheless there's something of me in the interpretation.
我不只是说“plastic“的意思是“塑料“,但无论如何在解读中总是有“我“的成分。

-
It operates in a similar fashion to DNA polymerase in that it denatures locally or opens up the double stranded DNA, but it's different in that it creates a new polymer from the DNA template in the language of RNA, using RNA nucleotides and not DNA nucleotides.
它的作用机制类似于DNA聚合酶,在局部使DNA双链变性,解旋,但不同的是,它合成了一个基于DNA模板的,使用RNA编码语言的新聚合物,即使用核糖核苷而非脱氧核糖核苷
