组蛋白是一种存在于真核细胞核中的碱性蛋白质,与DNA结合形成染色质结构,参与基因表达调控。

用法要点

句型搭配

histone通常作为名词使用,常见于描述其功能、修饰或与DNA的关系,如"histone modification"或"histone binds to DNA"。

• histone modification
• histone acetylation
• histone binds to DNA

介词用法

histone常与介词"in"、"of"、"with"搭配,表示位置、所属或关联,例如"histone in chromatin"或"modification of histone"。

• histone in chromatin
• modification of histone
• interact with histone

语域说明

histone是高度专业化的生物化学和分子生物学术语,主要用于学术、科研和医学领域,日常对话中极少使用。

• histone research
• histone in epigenetics
• histone-related diseases

基础例句

In biology class, we learned that histone helps package DNA into chromosomes.

在生物课上,我们学到组蛋白帮助将DNA包装成染色体。

The teacher explained how histone modifications can affect gene expression.

老师解释了组蛋白修饰如何影响基因表达。

I read an article about histone and its role in cell division.

我读了一篇关于组蛋白及其在细胞分裂中作用的文章。

高级例句

Recent studies show that histone acetylation is crucial for transcriptional activation in cancer cells.

最近研究表明,组蛋白乙酰化对癌细胞的转录激活至关重要。

The research team investigated histone methylation patterns in neurodegenerative diseases.

研究团队调查了神经退行性疾病中的组蛋白甲基化模式。

常见错误

❌ 错误:Histone is a type of DNA.
✓ 正确:Histone is a protein that binds to DNA.

错误地将组蛋白误认为是DNA的一种;实际上,组蛋白是蛋白质,与DNA结合形成染色质。

❌ 错误:Histone can be found in all cells.
✓ 正确:Histone is primarily found in eukaryotic cells.

错误地认为组蛋白存在于所有细胞中;实际上,组蛋白主要存在于真核细胞中,原核细胞通常没有组蛋白。

近义词辨析

chromatin

chromatin是DNA和组蛋白等蛋白质的复合物,而histone是其中的蛋白质组分;chromatin更强调结构整体。

Histone modifications alter chromatin structure to regulate gene expression.

nucleosome

nucleosome是染色质的基本单位,由DNA缠绕在组蛋白核心上形成;histone是构成nucleosome的蛋白质部分。

Each nucleosome contains eight histone proteins around which DNA is wrapped.
