1·Results all samples of water have plenty of direct mutagen and a small amount of indirect mutagen of base frameshift mutation.

结果各水样中有大量的碱基移码型的直接致突变物和少量的需经代谢活化的碱基移码型的直接致突变物。

2·In Ames assay the strains were TA98 and TA100, which were able to determine base pair substitutions and frameshift mutation respectively.

所用的菌种为TA98和TA10 0 ，主要考察碱基对置换突变和移码致突变。

3·The mutations in patients with factor V deficiency were identified including point mutation, frameshift mutation, deletion and insertion mutation.

本课题在对具有先天性出血倾向的门诊患者进行筛查的过程中，发现了一例重型凝血因子V缺乏症患者。

4·We show that sodium channels with the missense mutation recover from inactivation more rapidly than normal and that the frameshift mutation causes the sodium channel to be non-functional.

电生理研究显示含有错义突变的钠离子通道比正常通道从静止中恢复的更快，而读码突变使钠离子通道失去功能。
