染色质纤维是细胞核内由DNA和蛋白质组成的细长结构,负责储存和传递遗传信息。

用法要点

句型搭配

通常作为名词短语使用,在句子中作主语或宾语,描述细胞生物学中的结构或功能。

• The chromatin fiber is essential for gene regulation.
• Researchers observed the chromatin fiber under a microscope.
• Changes in chromatin fiber structure affect cell function.

介词用法

常与介词如 'in'、'of'、'by' 搭配,表示位置、组成或方式,例如 'in the nucleus' 或 'composed of DNA'。

• Chromatin fiber in eukaryotic cells is highly organized.
• The structure of chromatin fiber is complex.
• Gene expression is regulated by chromatin fiber modifications.

语域说明

主要用于学术和医学语境,如生物学、遗传学或医学研究,日常对话中较少使用,属于专业术语。

• In academic papers, chromatin fiber is often discussed in relation to epigenetics.
• Medical students learn about chromatin fiber in cell biology courses.
• This term is rarely used in casual conversations.

基础例句

常见错误

❌ 错误:Chromatin fiber is a simple string in the cell.
✓ 正确:Chromatin fiber is a complex structure composed of DNA and proteins in the cell nucleus.

错误用法过于简化,染色质纤维不是简单的'线',而是由DNA和蛋白质组成的复杂结构,位于细胞核内。正确用法应准确描述其组成和位置。

❌ 错误:I can see chromatin fiber with my eyes.
✓ 正确:Chromatin fiber can only be observed under a microscope due to its microscopic size.

错误用法暗示肉眼可见,但染色质纤维是微观结构,需要显微镜才能观察。正确用法应强调其微观性质和观察工具。

近义词辨析

chromosome

染色体是染色质纤维在细胞分裂时高度凝缩形成的可见结构,而染色质纤维是更基础的、非凝缩状态下的DNA-蛋白质复合物。

During interphase, chromatin fiber is loosely packed, but it condenses into chromosomes during mitosis.

chromatin

染色质是一个更广泛的术语,指细胞核中DNA和蛋白质的复合物,包括染色质纤维;染色质纤维特指其细长的纤维状结构。

Chromatin includes both euchromatin and heterochromatin, with chromatin fiber being its structural unit.
