base substitution

基本解釋

Furthermore, it is the first time that this single-base substitution mutation in AGTR2 gene was reported in X-linked mental retardation.
在伴性連鎖智障疾病中，AGTR2基因的這個單堿基替換突變位點為首次報道。
We cloned 466 bands to sequence. The sequencing results showed that the main mutation is base substitution, with occasional segment deletions and insertions.
我們克隆了466條變異序列測序分析，測序結果顯示突變的主要形式是堿基替換，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.
本研究同時提出了水稻稻米糊化溫度調控的分子遺傳假說，認為基因編碼區(qū)內堿基插入、缺失或替換可能是GT改變的遺傳基礎。
