Point mutation in codon 12 of Hras and Kras were detected by polymerase chain reactionrestriction fragment length polymorphism.

应用聚合酶链反应限制性片段长度多态性分析法检测Hras、Kras基因第12密码子点突变情况。

ConclusionThe point mutation rate of codon 12 of Hras and Kras is low in gastric cancer, which suggestive of little role in the genesis of the cancer.

胃癌组织中Hras、Kras基因第12密码子点突变率低，在胃癌的发生中不起主要作用。

The promoter is typically haloarchaeal, but the start site of transcription is only seven bases from the 5'end of the initiator AUG codon, making the halC8 transcript another example of a"leadless transcript"in the haloarchaea.

它的-29～-24位置上是一"TATA"box序列，为典型的嗜盐古菌启动子；它的转录起始位点距离"ATG"只有7个核苷酸，也是典型的嗜盐古菌的"leadless transcript"。

The are obvious biases in the both codon and amino acid usage in Lepidoptera species mitochondrial PCGs.NNU and NNA are the most frequently used codons.

鳞翅目昆虫的线粒体基因组中蛋白编码基因密码子的使用和氨基酸使用都有极强的偏向性，其中NNU和NNA密码子的使用频率相当的高。

The codon coding Leu is the site of high frequent mutation in α1- AT gene.

编码亮氨酸的密码子是突变发生的高频位点。

The selection pressure at the translation level is evident in all bacteria based on the analysis of the skew at the three codon positions.

基於三个转录子位置的碱基组态分析，转译层次上的筛选效应存在於所有的细菌当中。

This is because, in the a ence of any other knowledge, the DNA sequence can be tra lated or read in six po ible reading frames （three for each strand, corre onding to three different start positio for the first codon）.

这是因为在没有其它信息的前提下，DNA序列可以按六种框架阅读和翻译（每条链三种，对应三种不同的起始密码子）。

Cloning and sequencing of the genes coding a and 3 subunit of phycoerythrin of a red alga-Corallina officinalis are reported firstly(GenBankaccession number: AF510986). The sequence contain 1,140 nucleotide, including 10 nucleotide that locate in the upstream of the initiation codon ofP subunit, 534 coding for P subunit(coding 177 amino acid), 101 nucleotide for gene spacer and 495 nucleotide that draw near the 5 terminal of a subunit(coding 164 amino acid).

首次测定了珊瑚藻藻红蛋白α和β亚基基因的全序列(GenBank登录号：AF510986)，测定的基因序列长为1，140个碱基，包括β亚基起始密码子上游的10个碱基，6亚基编码区的534个碱基(编码177个氨基酸)，101个碱基的间隔区以及α亚基编码区近5'端的495个碱基(编码164个氨基酸)。

The transitions at the third codon positions of the COI data set were found saturated, but they were retained for analysis, because they contain the majority of the phylogenetic information.

虽然 COI 基因数据中第3位点的转换替换已达饱和，但由于这些位点含有大量系统发育信息，因而在数据统计分析时并没有将这些位点删除。

The difference between codon choice randomization in the region of protein regular secondary structure and that in coil region is investigated in detail. We find that the folding free energy of mRNA segments in different protein secondary structures is significantly different. The average Z score is -1. 38 and -1. 71 for regular secondary structure, but -0.93 and -1. 03 for coil.

我们仔细分析了在蛋白质规则结构区域（alpha螺旋和beta折叠）和无规则结构区域密码子随机选择的差异，发现处于不同蛋白质二级结构的mRNA片段的折叠自由能有显著的不同，对于规则结构，Human和E.coli的平均Z-score值分别为-1.71和-1.38，但是无规则结构的Z-score值分别为-1.03和-0.93。
