chromatid的音标是[ˈkrəumətid],基本翻译是“色单体”。速记技巧可以是结合其基本翻译的含义,与相关的词汇色(se色)和体(tǐ体)一起记忆。
chromatid这个词来源于希腊语中的“chroma”(颜色)和“tidos”(条)。它的意思是染色单体,即由一对姐妹染色单体组成的染色体的一部分。
chromatid的变化形式是复数形式,chromatids。

1. chromosome(染色体):由DNA和蛋白质组成的细胞中的遗传物质结构,是染色质的基本结构单位。
2. sisterchromatid(姐妹染色单体):来自同一着丝粒的染色单体,在有丝分裂和减数分裂过程中会分开并形成两个子染色体。
3. chromatism(色差):在光学或视觉系统中,由于物体颜色或照明条件不同而产生的颜色差异。

英文小作文:
Chromatids are the building blocks of chromosomes, and their structure and behavior play a crucial role in cell division and genetics research. Chromatids are formed by DNA replication during cell division, and they are made up of two strands of DNA that are held together by a protein structure called the centromere. During cell division, chromatids undergo various processes such as separation, duplication, and fusion, which are essential for proper chromosome segregation and cell division. Chromatid breakage and fusion can lead to genetic variation and mutation, which are important factors in evolution and genetic diseases. Understanding the structure and behavior of chromatids is crucial for understanding the basic principles of genetics and cell biology, and it has implications for medical and biological research.
