The statistical results show that the bases and dinucleotides with low contents are just associated with those in the stop codon tga 对单核苷酸和双核苷酸的使用进行统计分析，结果表明与终止密码子对应的组分的含量都很低。
All but three of the codons correspond to particular amino acids , and the order of the codons in the nucleic acid corresponds to the order of the amino acids in the protein 所有三个基码同特定的氨基酸相吻合，而基码在核酸中的顺序，同氨基酸在蛋白质中的顺序一致。
Rt - pcr were performed to obtain the information of transcriptional profile , the transcription stop site was mapped to 4bp downstream of stop codon tga by 3 ' race 对ha99基因作了相关的计算机分析，用rt - pcr方法从mrna水平上对该基因进行了鉴定，证明是一个晚期基因。
The genes in 11 microbial genomes with different g + c contents have been studied . it has been found that the distribution of bases at three codon positions is asymmetric 通过对11种具有不同g + c含量的微生物基因组进行分析，显示蛋白质编码区碱基分布具有不对称性。
Sv40 polya signal and two loxp sites was added consecutively after the termination codon taa , and then a gfp gene was inserted between the two loxp sites 在三个终止密码子taa之后，连上sv40polya 。 sv40polya之后，又连上两个loxp位点。在两个loxp位点，插入标记基因gfp 。
In order to improve the expression level of e2 gene in p . pastoris , 24 low - usage codons for p . pastoris were substitued by directed mutagnesis based on pcr 这表明对e2基因上低利用密码子的改造是成功的，猪瘟病毒ez基因遗传变异及体外表达研究为进一步大规模生产打下了基础。
All the authors are also scientific advisers to codon devices in cambridge , mass . , the first commercial enterprise launched to apply engineering principles to synthetic biology 他们共同撰写这篇文章，是因为彼此专长各异，对生物制程的发展有不同的贡献，代表了生物工程学跨学科的特色。
