- In the past few years, many new protocols for directed evolution were developed on the basis of oligonucleotide -directed random mutation, error-prone PCR and DNA shuffling. 最近几年,在过去常用的寡核苷酸介导的随机突变、易错PCR和DNA改组等方法的基础上又出现了一些新的定向进化方法。
- The dot's children varied in length depending on what value the random mutation assigned. 这个点的孩子们的长度随着随机变异赋以参数值而有所不同。
- These anomalies could arise if random mutation reversed the disablement that originally produced the pseudogene. 这种变异型的产生，可能是因为原本让基因失去功能、变成伪基因的缺损，因随机突变而修复了。
- Variation thus became mutation and "mutation" became inseparably compounded into "random mutation. 于是，变异（variation）就变成了突变（mutation），而“突变”又跟随机组合成不可分割的“随机突变”。

- The ID movement neither completely denied Darwinism,nor denied the existence of evolution,however,it mostly criticized Darwin and his adherents regard natural selection and random mutation as the uppermost and only root of evolution. ID运动没有全盘的否定达尔文主义,也不否定进化现象的存在,而是批评达尔文及其追随者把自然选择和随机突变作为进化现象最主要的、甚至唯一的根源。
