寡核苷酸是一种由少量核苷酸组成的短链核酸分子,常用于分子生物学研究和基因技术。

用法要点

句型搭配

通常作为名词使用,在句子中作主语、宾语或定语,常见于科技文献和学术讨论中。

• The oligonucleotide was synthesized for the experiment.
• They designed an oligonucleotide probe.
• Oligonucleotide synthesis is a key step.

介词用法

常与介词如 'for'、'in'、'with' 搭配,表示目的、领域或工具,例如用于实验或作为探针。

• Oligonucleotides for gene editing
• Used in PCR amplification
• Hybridize with target DNA

语域说明

主要出现在学术、科技和医学语境中,日常对话中较少使用,属于专业术语。

• In the lab, we use oligonucleotides daily.
• This paper discusses oligonucleotide applications.
• Oligonucleotide therapy is emerging.

基础例句

In biology class, we learned that oligonucleotides are short DNA strands.

在生物课上,我们学到寡核苷酸是短的DNA链。

The scientist used an oligonucleotide to detect the virus in the sample.

科学家用寡核苷酸检测样本中的病毒。

Can you explain what an oligonucleotide does in simple terms?

你能用简单的话解释寡核苷酸是做什么的吗?

高级例句

The research team developed a novel oligonucleotide-based drug for targeting cancer cells.

研究团队开发了一种新型的基于寡核苷酸的药物,用于靶向癌细胞。

In the conference, they presented data on oligonucleotide synthesis efficiency improvements.

在会议上,他们展示了关于寡核苷酸合成效率提升的数据。

Oligonucleotide microarrays are widely used in genomics for high-throughput analysis.

常见错误

❌ 错误:I need to buy an oligonucleotide from the store.
✓ 正确:I need to synthesize an oligonucleotide in the lab.

错误:寡核苷酸是专业化学或生物制品,通常不在普通商店出售,而是在实验室合成或订购。正确用法应强调其科技背景。

❌ 错误:Oligonucleotide is a long chain of nucleotides.
✓ 正确:Oligonucleotide is a short chain of nucleotides.

错误:寡核苷酸由少量核苷酸组成,是短链,而非长链。正确用法需准确描述其长度特征,避免与多核苷酸混淆。

近义词辨析

polynucleotide

多核苷酸指由许多核苷酸组成的长链核酸,如DNA或RNA,而寡核苷酸特指短链,通常少于50个核苷酸。

Polynucleotides like DNA are long chains, whereas oligonucleotides are short synthetic strands used in labs.

primer

引物是一种特定类型的寡核苷酸,用于启动DNA复制,如PCR中,但并非所有寡核苷酸都是引物;寡核苷酸更泛指短链核酸分子。

A primer is an oligonucleotide designed to initiate DNA synthesis, but oligonucleotides can also serve as probes or drugs.
