The adenovirus expression ribozyme inhibits hbv expressed in cell .

腺病毒介导核酶对细胞内hbv基因表达的抑制作用。

Joyce 's specialty is the creation of ribozyme systems that replicate and even evolve somewhat - on the verge of life , but not quite there .

乔伊斯专攻构建核酶系统，复制并演化的物体近乎生命，但还不是完全的生命。

For instance , a kind of rna called a ribozyme can cut up viral dna and trigger cell suicide to ensure the infection does not spread .

比如，一种称作核酶的核糖核酸（rna）可以切断病毒的dna，引发细胞自杀，从而确保感染不会扩散。

But the discovery that rna can be an enzyme , dubbed a ribozyme , potentially able to boost its own replication , led to fresh ideas about how life might have started .

但是这项发现表明，rna可能是种酶，且称之为核酶，它或许能促发自我复制，这就把生命如何起始引向新思路。
