n.转换，颠换，过程

In genetics, a transversion is a type of DNA mutation where a pyrimidine (C or T) is replaced with another pyrimidine or a purine (A or G)."
在遗传学中，转位突变是指DNA中一个嘧啶（C或T）被另一种嘧啶或嘌呤（A或G）替换的变异。
The analysis of the genetic sequence revealed a transversion in the gene responsible for sickle cell anemia.
对基因组序列的分析揭示了镰状细胞贫血症相关基因中的一个转位突变。
Transversions are less common than point mutations because they don't change the reading frame of the DNA.
转位突变不如点突变常见，因为它们不会改变DNA的阅读框架。
The effect of a transversion on protein function can be neutral, beneficial, or detrimental depending on the position.
转位突变对蛋白质功能的影响可能既无害、有益也可能有害，这取决于突变的位置。
Researchers use bioinformatics tools to identify and analyze transversions in large genomic datasets.
研究人员使用生物信息学工具来识别和分析大规模基因组数据中的转位突变。
During DNA replication, transversions can lead to errors that may cause genetic disorders.
在DNA复制过程中，转位突变可能导致遗传病。
In some cases, natural selection can favor transversions that provide resistance to environmental stress.
在某些情况下，自然选择可能会倾向于那些提供环境压力抵抗力的转位突变。
Understanding transversions helps in understanding the evolutionary history of species.
理解转位突变有助于我们了解物种的进化历程。
Mutation databases often include both point mutations and transversions.
突变数据库通常会记录包括点突变和转位突变在内的各种变异类型。
Pharmacogenomics studies often investigate the role of transversions in drug response variability.
药代基因组学研究常探究转位突变在药物反应变异中的作用。
