base substitution

基本解释

Furthermore, it is the first time that this single-base substitution mutation in AGTR2 gene was reported in X-linked mental retardation.
在伴性连锁智障疾病中，AGTR2基因的这个单碱基替换突变位点为首次报道。
We cloned 466 bands to sequence. The sequencing results showed that the main mutation is base substitution, with occasional segment deletions and insertions.
我们克隆了466条变异序列测序分析，测序结果显示突变的主要形式是碱基替换，只有少量的缺失，插入。
A hypothesis for molecular mechanism for GT variation of rice is presented, that is DNA insertion, deletion or base substitution in coding sequence of alk contributes to GT variation of rice.
本研究同时提出了水稻稻米糊化温度调控的分子遗传假说，认为基因编码区内碱基插入、缺失或替换可能是GT改变的遗传基础。
