从结构上来讲，基因包含三个区域：称为启动子的调节区域；与其并列的编码蛋白质的密码子区域；以及3'端尾部序列。
Structurally, a gene is formed by three regions: a regulatory region called the promoter juxtaposed to the coding region containing the protein sequence, and a “3’ tail” sequence.
每个密码子是特异的三核苷酸序列（双链DNA状况下为三个三核苷酸对），每个密码子编码蛋白质的一个氨基酸单位。
Each codon is a specific sequence of three nucleotides (three nucleotide pairs in double-stranded DNA), and each codon codes for a single amino acid unit in a protein.
它还带有特定的核苷酸序列即反密码子。
It also carries a specific nucleotide sequence, the anticodon.
DNA中的遗传信息是由连续的编码单位即密码子的线形序列构成的。
The genetic information contained in DNA consists of a linear sequence of successive coding units, known AS codons.
最初大家都只知道它的序列很短，是极其微小的RNA控制片断，大家叫它为反义RNA，它通过置换作用而阻止抑制基因的活性，从而阻碍密码子的转录与翻译活动。
It was previously known that short, tiny control RNA, called antisense RNA, can stop the activity of genes by placing themselves so that "reading" of the code is impeded.
在同义密码子重复序列中相同的密码子重复片段有非常明显的位置偏好。
There is distinct position bias for the same codon repeat segments in synonymous codon repeat sequences.
核苷酸序列变化主要表现在同义密码子的置换。
The variations of nucleotide mainly occurred the replace of synonymous codons.
序列分析表明该基因与日本株具有高度同源性，并且含有较高比例的稀有密码子。
Sequence analysis showed that its nucleotide sequence had high identity to a Japanese isolate of RDV and contained high percent of rare codons.
遗传信息的传递是从核酸序列三联密码子的转录和翻译，到合成具有完整结构的功能蛋白质的全过程。
The whole process of genetic information regulation and transduction involves three major steps: transcription and translation of the genetic code and the synthesis of the functional protein.
利用籼稻品种9311的全基因组序列及相应的EST数据，对影响同义密码子用法的若干因子进行了详细分析。
By using the whole genome sequences and EST data from the indica rice cultivar 93 11, a detailed relative analysis is made of the effect of some impact factors on synonymous codon usage.
