The experiment of adaptive mutation was performed by using Escherichia coli GM133 rif as test cells and HB214 strr as scavenger cells.
本研究采用大肠杆菌GM133 rif~r细胞和营养收集细胞HB214 sir~r进行适应性突变实验。
The research based on the Escherichia coli FC40 showed that adaptive mutations required the enzymes of RecBCD recombination pathway and some unknown proteins of SOS response,and the mutation spectrum of lac + revertants is single-base deletions in the small mononucleotide repeats.
基于大肠杆菌FC40菌株的研究结果表明 ,适应性突变依赖RecBCD重组途径的酶 ,要求SOS反应的部分基因功能 ,lac+ 回复突变序列都是在单核苷酸短重复序列处的一个碱基缺失。
