'nucleotide'并不是一个国家的语言,而是生物学中的一个专业术语。可以用中文翻译为“核苷酸”,是指DNA或RNA中一种由碱基、磷酸和五碳糖组成的分子。
常见翻译:核苷酸、核苷酸分子
用法:在生物学中,核苷酸是构成DNA和RNA的基本单元,是遗传信息的载体。此外,核苷酸还参与了许多生物代谢过程。
以下提供9个含有这个词语的例句:
1. Adenine is one of the four nucleotides that make up DNA.(腺嘌呤是构成DNA的四种核苷酸之一。)
2. The sequence of nucleotides in a strand of DNA determines the genetic code.(DNA链上的核苷酸序列决定了遗传密码。)
3. RNA is made up of a chain of nucleotides containing the bases adenine, guanine, cytosine, and uracil.(RNA由含有腺嘌呤、鸟嘌呤、胞嘧啶和尿嘧啶等碱基的核苷酸链组成。)
4. The structure of a nucleotide includes a nitrogenous base, a sugar molecule, and a phosphate group.(核苷酸的结构包括一种含氮碱基、一种糖分子和一个磷酸基团。)
5. The enzyme DNA polymerase combines nucleotides to form a new strand of DNA.(DNA聚合酶将核苷酸组合成新的DNA链。)
6. Mutations can occur when the sequence of nucleotides in DNA is altered.(当DNA中的核苷酸序列改变时,就会发生突变。)
7. The genetic code is translated from a sequence of nucleotides in mRNA to a sequence of amino acids in a protein.(遗传密码从mRNA中的核苷酸序列翻译成蛋白质中的氨基酸序列。)
8. Thymine is a pyrimidine nucleotide found in DNA, while uracil is a pyrimidine nucleotide found in RNA.(胸腺嘧啶是DNA中的嘧啶核苷酸,尿嘧啶是RNA中的嘧啶核苷酸。)
9. The polymerase chain reaction (PCR) is a technique used to amplify a specific sequence of nucleotides in DNA.(聚合酶链反应(PCR)是一种用于扩增DNA中特定核苷酸序列的技术。)
