用法要点

句型搭配

通常用作不可数名词,在句子中作主语或宾语,常见于被动语态或与动词搭配描述过程。

• The mutagenesis was induced by radiation.
• Scientists study the effects of mutagenesis on DNA.

介词用法

常与介词'by'连用表示诱变手段,如'by chemical mutagenesis';与'of'连用表示诱变对象,如'mutagenesis of genes'。

• Mutagenesis by UV light is common.
• Research focuses on mutagenesis of bacteria.

语域说明

主要用于学术、医学和科学语境,属于正式术语,日常对话中较少使用,但在科普讨论中可能出现。

• In lab reports, mutagenesis is a key term.
• The documentary explained mutagenesis simply.

基础例句

In biology class, we learned that mutagenesis can change an organism's traits.

在生物课上,我们学到诱变可以改变生物体的性状。

The scientist explained how mutagenesis helps in developing new crops.

常见错误

❌ 错误:Mutagenesis is a verb that means to change genes.
✓ 正确:Mutagenesis is a noun that refers to the process of inducing mutations.

错误:将mutagenesis误用为动词;正确:它是名词,描述诱变过程。应使用动词如'induce'搭配。

❌ 错误:The mutagenesis by the scientist was successful.
✓ 正确:The mutagenesis induced by the scientist was successful.

错误:介词'by'后直接跟施动者时,需用被动语态或添加动词;正确:加入'induced'使句子更完整自然。

近义词辨析

mutation

mutation指基因突变的结果或事件本身,而mutagenesis强调诱导突变的过程或方法。

A mutation occurred in the gene (结果) vs. Mutagenesis was used to create the mutation (过程)。

genetic alteration

genetic alteration是更广泛的术语,包括自然或人工的基因变化,而mutagenesis特指通过外部手段诱导的突变。

Genetic alteration can be spontaneous (自然) vs. Mutagenesis involves deliberate induction (人工)。
