Now they can and that helps keep the mutation in circulation.(不过现在可以了，这也助于让该突变维持流传。)
Are mutation rates universal?(这样的变异率是普遍的吗？)
People with this mutation are more or less immune to HIV infection.(带有这种突变的人对于艾滋病毒感染存在或多或少的免疫能力。)
While most disease-causing mutated are found in humans at a rate of one in a few thousand to one in a few million people, founder mutation can occur at much higher rates.(虽然大多数致病突变在人类中发现的概率为千分之一到百万分之一，但基础突变发生的几率可能高得多。)
This mutation has previously been identified in Viet Nam in one case in 2005.(这一突变以前在2005年越南的一个病例中曾得到鉴别。)
Imagine a new mutation arising in a gene.(设想一下在一个基因上发生了一个新的突变。)
Mutation of the tree while visiting.(在访问树的同时改变树。)
Constant mutation and adaptation are the survival mechanisms of pathogens.(不断变异和适应是病原体的生存机理。)
No pathogenic mutation was detected in the exon and franking regions of MYH9 gene except a synonymous mutation.(除同义突变外，在MYH9基因的外显子和弗兰克区域未检测到致病突变。)
Their allele frequencies at numerous genetic loci gradually become more and more different as new alleles independently arise by mutation in each population.(随着新等位基因在每个群体中独立突变产生，它们在许多遗传位点上的等位基因频率逐渐变得越来越不同。)
