常見例句雙語(yǔ)例句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(gè)單堿基替換突變位點(diǎn)為首次報(bào)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(cè)序分析，測(cè)序結(jié)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(shí)提出了水稻稻米糊化溫度調(diào)控的分子遺傳假說(shuō)，認(rèn)為基因編碼區(qū)內(nèi)堿基插入、缺失或替換可能是GT改變的遺傳基礎(chǔ)。 返回 base substitution
