In the NPC tissue ( 1 case only ) showing the prototype of Wt-XhoI / BamHI f , there were several base substitutions , including 5 missense mutations and 2 silent mutations present in LMP1 exon 3 , on DNA sequencing .

结果有6例患者在第4外显子上检测到密码子277位点CTG→CTA的置换，导致亮氨酸的同义突变（L277L），属于单核苷酸多态性，发生率为8%（6/75）。

In result , A G → A transition in codon 277 was observed in exon 4 in six patients . This variation leads to a nonsense mutation ( L277L ) and is a previously described polymorphism , the rate of variation is 8 % ( 6 / 75 ) .

11 nucleotide mutation sites were discovered in the 82 M genes , 9 of which were nonsynonymous mutation and 2 synonymous mutation .

与CV777及Br1/87核苷酸序列以及氨基酸遗传衍化关系分析显示，PEDV-QH株M基因的变异主要属于同义突变。

Sequences of nucleotides and amino acids correspondingly genetic derivation analysis showed that the mutation of M gene was belong to synonymous mutation mainly .

结果96例中有14例发现了8种突变，5种错义突变，1种同义突变，1种无义突变，1种移码突变。

Results 8 mutations were detected from 14 cases , including 5 missense mutations , 1 synonymous mutation , 1 nonsense mutation and 1 frameshift mutation .

Mutation happened in multiple sites of Red glandular honeysuckle , there are there missense mutations , the other two are same sense mutations without changes of amino acids .

9例为点突变，其中错义突变4例、无义突变2例、同义突变3例，其余2例为碱基插入和缺失导致的移码突变。

There were 9 point mutations , including 4 missense mutations , 2 nonsense mutations , 3 silent mutations . The other 2 cases were frameshift mutations due to base insertion and deletion .

撇开这一点不说，选择理论还能在解释基因序列和同义突变等新名词方面发挥作用，其影响范围之大，实在令人惊讶。

Despite our awareness of the wide reach of selection as an evolutionary force , its expanding sphere of influence for example , on gene order or synonymous mutations continues to surprise us .
