chromatin的音标为["krəʊmətɪn],翻译为“染色体”或“染色质”。
速记技巧:可以将chromatin拆分为chroma(染色)+ tion(名词后缀),在记忆时可联想到染色体是一种由DNA等物质组成的细胞结构。
Chromatin的英文词源是chromo,意为“色”,加上词缀-atin,表示“状态”。Chromatin意为“染色质”,是细胞中一种重要的染色物质。
Chromatin的变化形式如下:
1. Chromatin的过去式是chromatified,现在分词是chromatifying。
2. Chromatin的复数形式是chromosomes。
相关单词举例:
1. Chromosome(染色体):是一种由染色质构成的细胞结构,是遗传物质DNA的主要载体。
2. Interchromosome(染色体间):指在细胞分裂过程中,不同染色体之间发生的相互作用。
3. Chromosome Density(染色体密度):指的是在特定条件下,染色体在细胞中的相对数量。
Chromatin在生物学中非常重要,因为它涉及到细胞分裂和遗传学等多个领域的研究。同时,它也是许多生物技术中的重要组成部分,如DNA测序和基因表达分析等。
常用短语:
1. chromatin remodeling
2. chromatin modification
3. chromatin immunoprecipitation (ChIP)
4. chromatin binding
5. chromatin condensation
6. chromatin decondensation
7. chromatin fragmentation
例句:
1. The enzyme can modify chromatin structure to regulate gene expression.
2. The binding of transcription factors to chromatin regulates gene expression.
3. Chromatin condensation occurs during cell division to package DNA.
4. Chromatin decondensation is necessary for DNA replication.
5. Chromatin fragmentation is a characteristic of apoptosis.
6. Chromatin remodeling is crucial for proper gene expression in response to external stimuli.
英文小作文:
Chromatin is the basic structural unit of DNA, and it plays a crucial role in gene expression and cell function. Chromatin remodeling, modification, condensation, decondensation, and fragmentation are essential processes that regulate gene expression and maintain cellular homeostasis. Chromatin also plays a role in DNA repair and other cellular processes. Understanding chromatin structure and function is crucial for understanding human health and disease, and for developing effective therapeutic strategies.
