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.

结果构建的EBO G87和EBO WT重组载体经内切酶双酶切鉴定及核苷酸序列测定证实。

Results The constructed vectors of EBO-WT and EBO-G87 were identified by restriction enzyme digestion and nucleotide sequencing.

本实验对生物素化补骨脂素标记核酸的条件和效果进行了研究，发现该试剂不仅能标记双链dna、单链dna，更重要的是可以直接标记RNA及寡核苷酸。

We have systematically studied the relations between the probe labelling effects and conditions, and found that it not only can label dsDNA, ssDNA, but also RNA and oligonucleotide.

Now, in your book, there's an example of plasmid where I've given you the exact sequence of nucleotides that makes up the whole double stranded DNA molecule.

现在在你们书里,有个质粒样本,我将组成这个双链DNA分子的,核苷酸序列写在这里了
