hypermutation meaning in English

超变体
高变，超变

Meanwhile , hypermutation is used to keep the population ' s diversity and overcome the prematurity
引入超变异算子维持种群的多样性，提高全局寻优能力。
Such cells could potentially give rise to cancers - - especially when they became functionally impaired by short telomere length - - but the progression of such cancers would be minimal because no telomere elongation system could be activated even by hypermutation
这样的细胞可能潜在地会长癌（特别是因端粒短而使它们的功能受到削弱），但这样的癌症进展是微不足道的，因为没有端粒延长系统可以被激活（哪怕是高突变率也不能激活）。
However , dna damage has been ruled out as the prerequisite for alkylating agents - induced mutagenesis . for example , somatic hypermutation , which occurred around the variable region in the immunoglobin gene of b cells , is driven by antigen activation not by dna damage and is considered a kind of active mutation
但是dna损伤并不是引起突变的必要条件，一个典型的例子就是发生在b淋巴细胞的免疫球蛋白( ig )可变区基因上的“体细胞超突变( somatichyermutation ) ” ，是由表面抗原受体而不是dna损伤驱动的主动突变。
