'RNA'这个词语来源于英语(RNA stands for “ribonucleic acid”)。RNA是一种核酸分子,与DNA密切相关,是生物体内重要的遗传信息的携带者之一。RNA通过转录(transcription)过程从DNA中制造出来,然后再通过翻译(translation)过程参与蛋白质合成。以下是9个带有RNA的例句:
1. RNA在细胞内起着至关重要的作用,它们是蛋白质合成的关键。
(RNA plays a crucial role in cells, serving as key players in protein synthesis.)
2. RNA序列的二级结构是决定其生物学功能的关键。
(The secondary structure of RNA sequences is crucial for determining their biological functions.)
3. 对RNA进行逆转录(reverse transcription)是研究病毒感染的重要手段。
(Reverse transcription of RNA is an important tool for studying viral infections.)
4. RNA编辑(RNA editing)是指在转录后的RNA序列上进行化学修饰的过程。
(RNA editing refers to the process of chemical modifications on RNA sequences after transcription.)
5. 研究RNA干扰(RNA interference)可以深入了解细胞内基因表达的调控机制。
(Studying RNA interference can provide insights into the regulatory mechanisms of gene expression in cells.)
6. 不同种类的RNA在特定的生物过程中扮演着不同的角色。
(Different types of RNA play different roles in specific biological processes.)
7. 人类基因组中的大多数DNA序列都是转录为RNA,但只有一小部分编码蛋白质。
(Most of the DNA sequences in the human genome are transcribed into RNA, but only a small portion of them encode proteins.)
8. RNA分子可以通过互补碱基配对与其他核酸分子结合,形成复杂的分子结构。
(RNA molecules can form complex molecular structures by binding to other nucleic acid molecules through complementary base pairing.)
9. RNA干扰技术可以应用于基因治疗、药物开发和农业生产等领域。
(RNA interference technology can be applied in various fields such as gene therapy, drug development, and agricultural production.)
